Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520596, here are decompositions:

17 + 31520579 = 31520596
59 + 31520537 = 31520596
113 + 31520483 = 31520596
179 + 31520417 = 31520596
197 + 31520399 = 31520596
257 + 31520339 = 31520596
353 + 31520243 = 31520596
479 + 31520117 = 31520596

Showing the first eight; more decompositions exist.
