Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597596, here are decompositions:

47 + 31597549 = 31597596
89 + 31597507 = 31597596
103 + 31597493 = 31597596
113 + 31597483 = 31597596
179 + 31597417 = 31597596
229 + 31597367 = 31597596
313 + 31597283 = 31597596
353 + 31597243 = 31597596

Showing the first eight; more decompositions exist.
