Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513466, here are decompositions:

43 + 31513423 = 31513466
157 + 31513309 = 31513466
163 + 31513303 = 31513466
349 + 31513117 = 31513466
409 + 31513057 = 31513466
433 + 31513033 = 31513466
463 + 31513003 = 31513466
643 + 31512823 = 31513466

Showing the first eight; more decompositions exist.
