Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606962, here are decompositions:

5 + 31606957 = 31606962
11 + 31606951 = 31606962
19 + 31606943 = 31606962
31 + 31606931 = 31606962
43 + 31606919 = 31606962
59 + 31606903 = 31606962
83 + 31606879 = 31606962
151 + 31606811 = 31606962

Showing the first eight; more decompositions exist.
