Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513674, here are decompositions:

7 + 31513667 = 31513674
13 + 31513661 = 31513674
53 + 31513621 = 31513674
61 + 31513613 = 31513674
67 + 31513607 = 31513674
113 + 31513561 = 31513674
251 + 31513423 = 31513674
263 + 31513411 = 31513674

Showing the first eight; more decompositions exist.
