Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627244, here are decompositions:

7 + 31627237 = 31627244
43 + 31627201 = 31627244
193 + 31627051 = 31627244
211 + 31627033 = 31627244
277 + 31626967 = 31627244
457 + 31626787 = 31627244
577 + 31626667 = 31627244
673 + 31626571 = 31627244

Showing the first eight; more decompositions exist.
