Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627088, here are decompositions:

19 + 31627069 = 31627088
37 + 31627051 = 31627088
61 + 31627027 = 31627088
109 + 31626979 = 31627088
379 + 31626709 = 31627088
397 + 31626691 = 31627088
421 + 31626667 = 31627088
499 + 31626589 = 31627088

Showing the first eight; more decompositions exist.
