Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627058, here are decompositions:

7 + 31627051 = 31627058
31 + 31627027 = 31627058
79 + 31626979 = 31627058
271 + 31626787 = 31627058
349 + 31626709 = 31627058
367 + 31626691 = 31627058
439 + 31626619 = 31627058
487 + 31626571 = 31627058

Showing the first eight; more decompositions exist.
