Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615676, here are decompositions:

7 + 31615669 = 31615676
13 + 31615663 = 31615676
67 + 31615609 = 31615676
73 + 31615603 = 31615676
193 + 31615483 = 31615676
199 + 31615477 = 31615676
277 + 31615399 = 31615676
439 + 31615237 = 31615676

Showing the first eight; more decompositions exist.
