Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607876, here are decompositions:

7 + 31607869 = 31607876
19 + 31607857 = 31607876
37 + 31607839 = 31607876
193 + 31607683 = 31607876
277 + 31607599 = 31607876
373 + 31607503 = 31607876
577 + 31607299 = 31607876
613 + 31607263 = 31607876

Showing the first eight; more decompositions exist.
