Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513734, here are decompositions:

13 + 31513721 = 31513734
37 + 31513697 = 31513734
41 + 31513693 = 31513734
67 + 31513667 = 31513734
73 + 31513661 = 31513734
113 + 31513621 = 31513734
127 + 31513607 = 31513734
173 + 31513561 = 31513734

Showing the first eight; more decompositions exist.
