Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607326, here are decompositions:

17 + 31607309 = 31607326
29 + 31607297 = 31607326
89 + 31607237 = 31607326
173 + 31607153 = 31607326
239 + 31607087 = 31607326
347 + 31606979 = 31607326
353 + 31606973 = 31607326
383 + 31606943 = 31607326

Showing the first eight; more decompositions exist.
