Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627044, here are decompositions:

11 + 31627033 = 31627044
17 + 31627027 = 31627044
37 + 31627007 = 31627044
67 + 31626977 = 31627044
101 + 31626943 = 31627044
151 + 31626893 = 31627044
257 + 31626787 = 31627044
277 + 31626767 = 31627044

Showing the first eight; more decompositions exist.
