Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597610, here are decompositions:

7 + 31597603 = 31597610
61 + 31597549 = 31597610
103 + 31597507 = 31597610
127 + 31597483 = 31597610
139 + 31597471 = 31597610
157 + 31597453 = 31597610
193 + 31597417 = 31597610
199 + 31597411 = 31597610

Showing the first eight; more decompositions exist.
