Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607584, here are decompositions:

3 + 31607581 = 31607584
5 + 31607579 = 31607584
53 + 31607531 = 31607584
137 + 31607447 = 31607584
227 + 31607357 = 31607584
257 + 31607327 = 31607584
293 + 31607291 = 31607584
347 + 31607237 = 31607584

Showing the first eight; more decompositions exist.
