Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613176, here are decompositions:

5 + 31613171 = 31613176
59 + 31613117 = 31613176
149 + 31613027 = 31613176
263 + 31612913 = 31613176
443 + 31612733 = 31613176
449 + 31612727 = 31613176
509 + 31612667 = 31613176
557 + 31612619 = 31613176

Showing the first eight; more decompositions exist.
