Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31490596, here are decompositions:

3 + 31490593 = 31490596
23 + 31490573 = 31490596
29 + 31490567 = 31490596
89 + 31490507 = 31490596
107 + 31490489 = 31490596
149 + 31490447 = 31490596
197 + 31490399 = 31490596
227 + 31490369 = 31490596

Showing the first eight; more decompositions exist.
