Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627962, here are decompositions:

13 + 31627949 = 31627962
31 + 31627931 = 31627962
59 + 31627903 = 31627962
73 + 31627889 = 31627962
83 + 31627879 = 31627962
101 + 31627861 = 31627962
151 + 31627811 = 31627962
199 + 31627763 = 31627962

Showing the first eight; more decompositions exist.
