Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607846, here are decompositions:

7 + 31607839 = 31607846
157 + 31607689 = 31607846
163 + 31607683 = 31607846
373 + 31607473 = 31607846
397 + 31607449 = 31607846
547 + 31607299 = 31607846
619 + 31607227 = 31607846
709 + 31607137 = 31607846

Showing the first eight; more decompositions exist.
