Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568584, here are decompositions:

23 + 31568561 = 31568584
41 + 31568543 = 31568584
167 + 31568417 = 31568584
191 + 31568393 = 31568584
197 + 31568387 = 31568584
227 + 31568357 = 31568584
251 + 31568333 = 31568584
317 + 31568267 = 31568584

Showing the first eight; more decompositions exist.
