Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597682, here are decompositions:

31 + 31597651 = 31597682
43 + 31597639 = 31597682
79 + 31597603 = 31597682
199 + 31597483 = 31597682
211 + 31597471 = 31597682
229 + 31597453 = 31597682
271 + 31597411 = 31597682
421 + 31597261 = 31597682

Showing the first eight; more decompositions exist.
