Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627084, here are decompositions:

11 + 31627073 = 31627084
107 + 31626977 = 31627084
191 + 31626893 = 31627084
227 + 31626857 = 31627084
257 + 31626827 = 31627084
317 + 31626767 = 31627084
521 + 31626563 = 31627084
647 + 31626437 = 31627084

Showing the first eight; more decompositions exist.
