Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607392, here are decompositions:

29 + 31607363 = 31607392
83 + 31607309 = 31607392
101 + 31607291 = 31607392
191 + 31607201 = 31607392
239 + 31607153 = 31607392
353 + 31607039 = 31607392
419 + 31606973 = 31607392
449 + 31606943 = 31607392

Showing the first eight; more decompositions exist.
