Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619834, here are decompositions:

13 + 31619821 = 31619834
73 + 31619761 = 31619834
151 + 31619683 = 31619834
223 + 31619611 = 31619834
277 + 31619557 = 31619834
307 + 31619527 = 31619834
313 + 31619521 = 31619834
523 + 31619311 = 31619834

Showing the first eight; more decompositions exist.
