Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606086, here are decompositions:

7 + 31606079 = 31606086
19 + 31606067 = 31606086
37 + 31606049 = 31606086
103 + 31605983 = 31606086
157 + 31605929 = 31606086
173 + 31605913 = 31606086
263 + 31605823 = 31606086
277 + 31605809 = 31606086

Showing the first eight; more decompositions exist.
