Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613156, here are decompositions:

13 + 31613143 = 31613156
19 + 31613137 = 31613156
37 + 31613119 = 31613156
103 + 31613053 = 31613156
283 + 31612873 = 31613156
397 + 31612759 = 31613156
409 + 31612747 = 31613156
643 + 31612513 = 31613156

Showing the first eight; more decompositions exist.
