Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607368, here are decompositions:

5 + 31607363 = 31607368
11 + 31607357 = 31607368
41 + 31607327 = 31607368
59 + 31607309 = 31607368
71 + 31607297 = 31607368
131 + 31607237 = 31607368
167 + 31607201 = 31607368
281 + 31607087 = 31607368

Showing the first eight; more decompositions exist.
