Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607758, here are decompositions:

11 + 31607747 = 31607758
41 + 31607717 = 31607758
71 + 31607687 = 31607758
179 + 31607579 = 31607758
227 + 31607531 = 31607758
269 + 31607489 = 31607758
311 + 31607447 = 31607758
359 + 31607399 = 31607758

Showing the first eight; more decompositions exist.
