Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552256, here are decompositions:

3 + 31552253 = 31552256
19 + 31552237 = 31552256
199 + 31552057 = 31552256
223 + 31552033 = 31552256
277 + 31551979 = 31552256
397 + 31551859 = 31552256
499 + 31551757 = 31552256
523 + 31551733 = 31552256

Showing the first eight; more decompositions exist.
