Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619676, here are decompositions:

7 + 31619669 = 31619676
29 + 31619647 = 31619676
59 + 31619617 = 31619676
73 + 31619603 = 31619676
149 + 31619527 = 31619676
157 + 31619519 = 31619676
167 + 31619509 = 31619676
269 + 31619407 = 31619676

Showing the first eight; more decompositions exist.
