Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513796, here are decompositions:

3 + 31513793 = 31513796
103 + 31513693 = 31513796
373 + 31513423 = 31513796
463 + 31513333 = 31513796
487 + 31513309 = 31513796
577 + 31513219 = 31513796
673 + 31513123 = 31513796
733 + 31513063 = 31513796

Showing the first eight; more decompositions exist.
