Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613944, here are decompositions:

17 + 31613927 = 31613944
83 + 31613861 = 31613944
101 + 31613843 = 31613944
137 + 31613807 = 31613944
227 + 31613717 = 31613944
317 + 31613627 = 31613944
431 + 31613513 = 31613944
503 + 31613441 = 31613944

Showing the first eight; more decompositions exist.
