Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608564, here are decompositions:

37 + 31608527 = 31608564
67 + 31608497 = 31608564
83 + 31608481 = 31608564
137 + 31608427 = 31608564
223 + 31608341 = 31608564
227 + 31608337 = 31608564
263 + 31608301 = 31608564
293 + 31608271 = 31608564

Showing the first eight; more decompositions exist.
