Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606108, here are decompositions:

11 + 31606097 = 31606108
29 + 31606079 = 31606108
41 + 31606067 = 31606108
47 + 31606061 = 31606108
59 + 31606049 = 31606108
137 + 31605971 = 31606108
179 + 31605929 = 31606108
389 + 31605719 = 31606108

Showing the first eight; more decompositions exist.
