Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607338, here are decompositions:

11 + 31607327 = 31607338
29 + 31607309 = 31607338
41 + 31607297 = 31607338
47 + 31607291 = 31607338
101 + 31607237 = 31607338
131 + 31607207 = 31607338
137 + 31607201 = 31607338
251 + 31607087 = 31607338

Showing the first eight; more decompositions exist.
