Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606056, here are decompositions:

5 + 31606051 = 31606056
7 + 31606049 = 31606056
73 + 31605983 = 31606056
103 + 31605953 = 31606056
127 + 31605929 = 31606056
179 + 31605877 = 31606056
233 + 31605823 = 31606056
277 + 31605779 = 31606056

Showing the first eight; more decompositions exist.
