Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513914, here are decompositions:

23 + 31513891 = 31513914
37 + 31513877 = 31513914
41 + 31513873 = 31513914
71 + 31513843 = 31513914
83 + 31513831 = 31513914
97 + 31513817 = 31513914
127 + 31513787 = 31513914
193 + 31513721 = 31513914

Showing the first eight; more decompositions exist.
