Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627508, here are decompositions:

7 + 31627501 = 31627508
97 + 31627411 = 31627508
151 + 31627357 = 31627508
271 + 31627237 = 31627508
307 + 31627201 = 31627508
439 + 31627069 = 31627508
457 + 31627051 = 31627508
541 + 31626967 = 31627508

Showing the first eight; more decompositions exist.
