Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627948, here are decompositions:

17 + 31627931 = 31627948
59 + 31627889 = 31627948
137 + 31627811 = 31627948
197 + 31627751 = 31627948
227 + 31627721 = 31627948
347 + 31627601 = 31627948
389 + 31627559 = 31627948
557 + 31627391 = 31627948

Showing the first eight; more decompositions exist.
