Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597662, here are decompositions:

11 + 31597651 = 31597662
23 + 31597639 = 31597662
59 + 31597603 = 31597662
113 + 31597549 = 31597662
179 + 31597483 = 31597662
191 + 31597471 = 31597662
251 + 31597411 = 31597662
379 + 31597283 = 31597662

Showing the first eight; more decompositions exist.
