Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619586, here are decompositions:

29 + 31619557 = 31619586
43 + 31619543 = 31619586
59 + 31619527 = 31619586
67 + 31619519 = 31619586
127 + 31619459 = 31619586
179 + 31619407 = 31619586
197 + 31619389 = 31619586
199 + 31619387 = 31619586

Showing the first eight; more decompositions exist.
