Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607324, here are decompositions:

31 + 31607293 = 31607324
43 + 31607281 = 31607324
61 + 31607263 = 31607324
97 + 31607227 = 31607324
223 + 31607101 = 31607324
277 + 31607047 = 31607324
367 + 31606957 = 31607324
373 + 31606951 = 31607324

Showing the first eight; more decompositions exist.
