Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619846, here are decompositions:

3 + 31619843 = 31619846
163 + 31619683 = 31619846
199 + 31619647 = 31619846
229 + 31619617 = 31619846
337 + 31619509 = 31619846
439 + 31619407 = 31619846
457 + 31619389 = 31619846
487 + 31619359 = 31619846

Showing the first eight; more decompositions exist.
