Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627716, here are decompositions:

67 + 31627649 = 31627716
89 + 31627627 = 31627716
139 + 31627577 = 31627716
149 + 31627567 = 31627716
157 + 31627559 = 31627716
173 + 31627543 = 31627716
179 + 31627537 = 31627716
233 + 31627483 = 31627716

Showing the first eight; more decompositions exist.
