Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552244, here are decompositions:

7 + 31552237 = 31552244
37 + 31552207 = 31552244
211 + 31552033 = 31552244
307 + 31551937 = 31552244
463 + 31551781 = 31552244
487 + 31551757 = 31552244
523 + 31551721 = 31552244
631 + 31551613 = 31552244

Showing the first eight; more decompositions exist.
