Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613630, here are decompositions:

3 + 31613627 = 31613630
7 + 31613623 = 31613630
79 + 31613551 = 31613630
193 + 31613437 = 31613630
229 + 31613401 = 31613630
439 + 31613191 = 31613630
487 + 31613143 = 31613630
523 + 31613107 = 31613630

Showing the first eight; more decompositions exist.
