Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609436, here are decompositions:

43 + 31609393 = 31609436
97 + 31609339 = 31609436
223 + 31609213 = 31609436
349 + 31609087 = 31609436
499 + 31608937 = 31609436
613 + 31608823 = 31609436
619 + 31608817 = 31609436
643 + 31608793 = 31609436

Showing the first eight; more decompositions exist.
