Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31519676, here are decompositions:

3 + 31519673 = 31519676
109 + 31519567 = 31519676
157 + 31519519 = 31519676
193 + 31519483 = 31519676
313 + 31519363 = 31519676
379 + 31519297 = 31519676
577 + 31519099 = 31519676
607 + 31519069 = 31519676

Showing the first eight; more decompositions exist.
