Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613582, here are decompositions:

3 + 31613579 = 31613582
31 + 31613551 = 31613582
43 + 31613539 = 31613582
181 + 31613401 = 31613582
199 + 31613383 = 31613582
241 + 31613341 = 31613582
439 + 31613143 = 31613582
463 + 31613119 = 31613582

Showing the first eight; more decompositions exist.
