Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 97640, here are decompositions:

31 + 97609 = 97640
61 + 97579 = 97640
79 + 97561 = 97640
139 + 97501 = 97640
181 + 97459 = 97640
199 + 97441 = 97640
211 + 97429 = 97640
271 + 97369 = 97640

Showing the first eight; more decompositions exist.
