Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613874, here are decompositions:

7 + 31613867 = 31613874
13 + 31613861 = 31613874
31 + 31613843 = 31613874
41 + 31613833 = 31613874
67 + 31613807 = 31613874
73 + 31613801 = 31613874
157 + 31613717 = 31613874
251 + 31613623 = 31613874

Showing the first eight; more decompositions exist.
