Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499584, here are decompositions:

23 + 31499561 = 31499584
47 + 31499537 = 31499584
173 + 31499411 = 31499584
197 + 31499387 = 31499584
257 + 31499327 = 31499584
293 + 31499291 = 31499584
317 + 31499267 = 31499584
353 + 31499231 = 31499584

Showing the first eight; more decompositions exist.
