Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589584, here are decompositions:

17 + 31589567 = 31589584
23 + 31589561 = 31589584
71 + 31589513 = 31589584
101 + 31589483 = 31589584
251 + 31589333 = 31589584
263 + 31589321 = 31589584
281 + 31589303 = 31589584
293 + 31589291 = 31589584

Showing the first eight; more decompositions exist.
