Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567118, here are decompositions:

31 + 31567087 = 31567118
139 + 31566979 = 31567118
151 + 31566967 = 31567118
199 + 31566919 = 31567118
409 + 31566709 = 31567118
487 + 31566631 = 31567118
571 + 31566547 = 31567118
577 + 31566541 = 31567118

Showing the first eight; more decompositions exist.
