Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507706, here are decompositions:

3 + 31507703 = 31507706
7 + 31507699 = 31507706
73 + 31507633 = 31507706
199 + 31507507 = 31507706
409 + 31507297 = 31507706
463 + 31507243 = 31507706
547 + 31507159 = 31507706
619 + 31507087 = 31507706

Showing the first eight; more decompositions exist.
