Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31551596, here are decompositions:

3 + 31551593 = 31551596
19 + 31551577 = 31551596
79 + 31551517 = 31551596
277 + 31551319 = 31551596
313 + 31551283 = 31551596
337 + 31551259 = 31551596
409 + 31551187 = 31551596
457 + 31551139 = 31551596

Showing the first eight; more decompositions exist.
