Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31551776, here are decompositions:

19 + 31551757 = 31551776
43 + 31551733 = 31551776
163 + 31551613 = 31551776
199 + 31551577 = 31551776
229 + 31551547 = 31551776
367 + 31551409 = 31551776
457 + 31551319 = 31551776
499 + 31551277 = 31551776

Showing the first eight; more decompositions exist.
