### Prime Number Upside down

Prime Number upside down
If you type the prime 3217001 on a calculator and hold it upside down, you can read the word "IDOLIZE", provided you accept that '0' can be both "D" and "O". Are there any larger primes that become a meaningful word when read upside down like this?

1. Well there are around 1M words in the english dictionary.
You could loop over the words and check
Any other ingenious method ?

2. Not sure about any ingenious method. But if i ll have to do it, i would better identify the digits that look like alphabets and try to find their permutation or combination first. The to eliminate further i would not look for words without vowels and with more than 2-3 vowels/consonants together.
Any more thoughts??

3. Here are few:
3718103 = edibile
5355307 = loesses
5734051 = isohels
53517001 = idolises
55076051 = isogloss
55373603 = edgeless
77185181 = ibisbill
378163771 = illegible
537816173 = eligibles
3216070301 = ideologize
03216070301 = ideologized
