Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597626, here are decompositions:

13 + 31597613 = 31597626
23 + 31597603 = 31597626
173 + 31597453 = 31597626
373 + 31597253 = 31597626
383 + 31597243 = 31597626
449 + 31597177 = 31597626
499 + 31597127 = 31597626
677 + 31596949 = 31597626

Showing the first eight; more decompositions exist.
