Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627954, here are decompositions:

5 + 31627949 = 31627954
23 + 31627931 = 31627954
191 + 31627763 = 31627954
227 + 31627727 = 31627954
233 + 31627721 = 31627954
353 + 31627601 = 31627954
443 + 31627511 = 31627954
563 + 31627391 = 31627954

Showing the first eight; more decompositions exist.
