Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627806, here are decompositions:

5 + 31627801 = 31627806
13 + 31627793 = 31627806
43 + 31627763 = 31627806
53 + 31627753 = 31627806
79 + 31627727 = 31627806
157 + 31627649 = 31627806
167 + 31627639 = 31627806
179 + 31627627 = 31627806

Showing the first eight; more decompositions exist.
