Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607422, here are decompositions:

23 + 31607399 = 31607422
59 + 31607363 = 31607422
113 + 31607309 = 31607422
131 + 31607291 = 31607422
269 + 31607153 = 31607422
383 + 31607039 = 31607422
443 + 31606979 = 31607422
449 + 31606973 = 31607422

Showing the first eight; more decompositions exist.
