Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613624, here are decompositions:

43 + 31613581 = 31613624
73 + 31613551 = 31613624
223 + 31613401 = 31613624
241 + 31613383 = 31613624
283 + 31613341 = 31613624
397 + 31613227 = 31613624
433 + 31613191 = 31613624
487 + 31613137 = 31613624

Showing the first eight; more decompositions exist.
