Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517596, here are decompositions:

17 + 31517579 = 31517596
23 + 31517573 = 31517596
53 + 31517543 = 31517596
179 + 31517417 = 31517596
197 + 31517399 = 31517596
353 + 31517243 = 31517596
389 + 31517207 = 31517596
557 + 31517039 = 31517596

Showing the first eight; more decompositions exist.
