Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613914, here are decompositions:

47 + 31613867 = 31613914
53 + 31613861 = 31613914
71 + 31613843 = 31613914
107 + 31613807 = 31613914
113 + 31613801 = 31613914
131 + 31613783 = 31613914
197 + 31613717 = 31613914
401 + 31613513 = 31613914

Showing the first eight; more decompositions exist.
