Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607322, here are decompositions:

13 + 31607309 = 31607322
23 + 31607299 = 31607322
29 + 31607293 = 31607322
31 + 31607291 = 31607322
41 + 31607281 = 31607322
59 + 31607263 = 31607322
283 + 31607039 = 31607322
349 + 31606973 = 31607322

Showing the first eight; more decompositions exist.
