Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597652, here are decompositions:

13 + 31597639 = 31597652
103 + 31597549 = 31597652
181 + 31597471 = 31597652
199 + 31597453 = 31597652
241 + 31597411 = 31597652
409 + 31597243 = 31597652
421 + 31597231 = 31597652
439 + 31597213 = 31597652

Showing the first eight; more decompositions exist.
