Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513962, here are decompositions:

5 + 31513957 = 31513962
19 + 31513943 = 31513962
71 + 31513891 = 31513962
83 + 31513879 = 31513962
89 + 31513873 = 31513962
113 + 31513849 = 31513962
131 + 31513831 = 31513962
223 + 31513739 = 31513962

Showing the first eight; more decompositions exist.
