Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606110, here are decompositions:

13 + 31606097 = 31606110
23 + 31606087 = 31606110
31 + 31606079 = 31606110
43 + 31606067 = 31606110
59 + 31606051 = 31606110
61 + 31606049 = 31606110
127 + 31605983 = 31606110
139 + 31605971 = 31606110

Showing the first eight; more decompositions exist.
