Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609316, here are decompositions:

103 + 31609213 = 31609316
127 + 31609189 = 31609316
199 + 31609117 = 31609316
223 + 31609093 = 31609316
229 + 31609087 = 31609316
283 + 31609033 = 31609316
379 + 31608937 = 31609316
433 + 31608883 = 31609316

Showing the first eight; more decompositions exist.
