Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613126, here are decompositions:

7 + 31613119 = 31613126
19 + 31613107 = 31613126
73 + 31613053 = 31613126
157 + 31612969 = 31613126
367 + 31612759 = 31613126
373 + 31612753 = 31613126
379 + 31612747 = 31613126
397 + 31612729 = 31613126

Showing the first eight; more decompositions exist.
