Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546670, here are decompositions:

7 + 31546663 = 31546670
13 + 31546657 = 31546670
37 + 31546633 = 31546670
73 + 31546597 = 31546670
79 + 31546591 = 31546670
97 + 31546573 = 31546670
277 + 31546393 = 31546670
283 + 31546387 = 31546670

Showing the first eight; more decompositions exist.
