Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606974, here are decompositions:

11 + 31606963 = 31606974
17 + 31606957 = 31606974
23 + 31606951 = 31606974
31 + 31606943 = 31606974
43 + 31606931 = 31606974
71 + 31606903 = 31606974
127 + 31606847 = 31606974
163 + 31606811 = 31606974

Showing the first eight; more decompositions exist.
