Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607752, here are decompositions:

5 + 31607747 = 31607752
173 + 31607579 = 31607752
263 + 31607489 = 31607752
353 + 31607399 = 31607752
389 + 31607363 = 31607752
443 + 31607309 = 31607752
461 + 31607291 = 31607752
599 + 31607153 = 31607752

Showing the first eight; more decompositions exist.
