Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607946, here are decompositions:

37 + 31607909 = 31607946
43 + 31607903 = 31607946
79 + 31607867 = 31607946
89 + 31607857 = 31607946
107 + 31607839 = 31607946
157 + 31607789 = 31607946
163 + 31607783 = 31607946
199 + 31607747 = 31607946

Showing the first eight; more decompositions exist.
