Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609134, here are decompositions:

17 + 31609117 = 31609134
23 + 31609111 = 31609134
41 + 31609093 = 31609134
43 + 31609091 = 31609134
47 + 31609087 = 31609134
101 + 31609033 = 31609134
103 + 31609031 = 31609134
163 + 31608971 = 31609134

Showing the first eight; more decompositions exist.
