Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619616, here are decompositions:

5 + 31619611 = 31619616
13 + 31619603 = 31619616
59 + 31619557 = 31619616
73 + 31619543 = 31619616
89 + 31619527 = 31619616
97 + 31619519 = 31619616
107 + 31619509 = 31619616
157 + 31619459 = 31619616

Showing the first eight; more decompositions exist.
