Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514004, here are decompositions:

17 + 31513987 = 31514004
37 + 31513967 = 31514004
47 + 31513957 = 31514004
61 + 31513943 = 31514004
113 + 31513891 = 31514004
127 + 31513877 = 31514004
131 + 31513873 = 31514004
173 + 31513831 = 31514004

Showing the first eight; more decompositions exist.
