Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463016, here are decompositions:

37 + 31462979 = 31463016
47 + 31462969 = 31463016
83 + 31462933 = 31463016
107 + 31462909 = 31463016
127 + 31462889 = 31463016
139 + 31462877 = 31463016
223 + 31462793 = 31463016
257 + 31462759 = 31463016

Showing the first eight; more decompositions exist.
