Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513714, here are decompositions:

5 + 31513709 = 31513714
17 + 31513697 = 31513714
47 + 31513667 = 31513714
53 + 31513661 = 31513714
101 + 31513613 = 31513714
107 + 31513607 = 31513714
311 + 31513403 = 31513714
383 + 31513331 = 31513714

Showing the first eight; more decompositions exist.
