Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607536, here are decompositions:

5 + 31607531 = 31607536
47 + 31607489 = 31607536
89 + 31607447 = 31607536
113 + 31607423 = 31607536
137 + 31607399 = 31607536
173 + 31607363 = 31607536
179 + 31607357 = 31607536
227 + 31607309 = 31607536

Showing the first eight; more decompositions exist.
