Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619636, here are decompositions:

19 + 31619617 = 31619636
79 + 31619557 = 31619636
109 + 31619527 = 31619636
127 + 31619509 = 31619636
229 + 31619407 = 31619636
277 + 31619359 = 31619636
379 + 31619257 = 31619636
457 + 31619179 = 31619636

Showing the first eight; more decompositions exist.
