Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609122, here are decompositions:

5 + 31609117 = 31609122
11 + 31609111 = 31609122
29 + 31609093 = 31609122
31 + 31609091 = 31609122
43 + 31609079 = 31609122
73 + 31609049 = 31609122
89 + 31609033 = 31609122
151 + 31608971 = 31609122

Showing the first eight; more decompositions exist.
