Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619534, here are decompositions:

3 + 31619531 = 31619534
7 + 31619527 = 31619534
13 + 31619521 = 31619534
127 + 31619407 = 31619534
223 + 31619311 = 31619534
277 + 31619257 = 31619534
643 + 31618891 = 31619534
757 + 31618777 = 31619534

Showing the first eight; more decompositions exist.
