Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607510, here are decompositions:

7 + 31607503 = 31607510
37 + 31607473 = 31607510
61 + 31607449 = 31607510
211 + 31607299 = 31607510
229 + 31607281 = 31607510
283 + 31607227 = 31607510
373 + 31607137 = 31607510
409 + 31607101 = 31607510

Showing the first eight; more decompositions exist.
