Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597892, here are decompositions:

13 + 31597879 = 31597892
19 + 31597873 = 31597892
163 + 31597729 = 31597892
199 + 31597693 = 31597892
241 + 31597651 = 31597892
409 + 31597483 = 31597892
421 + 31597471 = 31597892
439 + 31597453 = 31597892

Showing the first eight; more decompositions exist.
