Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613606, here are decompositions:

67 + 31613539 = 31613606
223 + 31613383 = 31613606
229 + 31613377 = 31613606
379 + 31613227 = 31613606
463 + 31613143 = 31613606
487 + 31613119 = 31613606
499 + 31613107 = 31613606
733 + 31612873 = 31613606

Showing the first eight; more decompositions exist.
