Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595596, here are decompositions:

3 + 31595593 = 31595596
23 + 31595573 = 31595596
29 + 31595567 = 31595596
113 + 31595483 = 31595596
233 + 31595363 = 31595596
317 + 31595279 = 31595596
353 + 31595243 = 31595596
359 + 31595237 = 31595596

Showing the first eight; more decompositions exist.
