Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627768, here are decompositions:

5 + 31627763 = 31627768
17 + 31627751 = 31627768
41 + 31627727 = 31627768
47 + 31627721 = 31627768
167 + 31627601 = 31627768
191 + 31627577 = 31627768
257 + 31627511 = 31627768
449 + 31627319 = 31627768

Showing the first eight; more decompositions exist.
