Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607504, here are decompositions:

31 + 31607473 = 31607504
43 + 31607461 = 31607504
163 + 31607341 = 31607504
211 + 31607293 = 31607504
223 + 31607281 = 31607504
241 + 31607263 = 31607504
277 + 31607227 = 31607504
367 + 31607137 = 31607504

Showing the first eight; more decompositions exist.
