Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609376, here are decompositions:

37 + 31609339 = 31609376
109 + 31609267 = 31609376
163 + 31609213 = 31609376
283 + 31609093 = 31609376
439 + 31608937 = 31609376
523 + 31608853 = 31609376
619 + 31608757 = 31609376
709 + 31608667 = 31609376

Showing the first eight; more decompositions exist.
