Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607274, here are decompositions:

11 + 31607263 = 31607274
37 + 31607237 = 31607274
47 + 31607227 = 31607274
67 + 31607207 = 31607274
73 + 31607201 = 31607274
137 + 31607137 = 31607274
173 + 31607101 = 31607274
227 + 31607047 = 31607274

Showing the first eight; more decompositions exist.
