Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627108, here are decompositions:

17 + 31627091 = 31627108
101 + 31627007 = 31627108
131 + 31626977 = 31627108
239 + 31626869 = 31627108
251 + 31626857 = 31627108
269 + 31626839 = 31627108
281 + 31626827 = 31627108
311 + 31626797 = 31627108

Showing the first eight; more decompositions exist.
