Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609086, here are decompositions:

7 + 31609079 = 31609086
37 + 31609049 = 31609086
53 + 31609033 = 31609086
127 + 31608959 = 31609086
149 + 31608937 = 31609086
193 + 31608893 = 31609086
199 + 31608887 = 31609086
233 + 31608853 = 31609086

Showing the first eight; more decompositions exist.
