Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619634, here are decompositions:

17 + 31619617 = 31619634
23 + 31619611 = 31619634
31 + 31619603 = 31619634
73 + 31619561 = 31619634
103 + 31619531 = 31619634
107 + 31619527 = 31619634
113 + 31619521 = 31619634
227 + 31619407 = 31619634

Showing the first eight; more decompositions exist.
