Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627422, here are decompositions:

11 + 31627411 = 31627422
31 + 31627391 = 31627422
89 + 31627333 = 31627422
103 + 31627319 = 31627422
173 + 31627249 = 31627422
179 + 31627243 = 31627422
271 + 31627151 = 31627422
331 + 31627091 = 31627422

Showing the first eight; more decompositions exist.
