Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567036, here are decompositions:

173 + 31566863 = 31567036
197 + 31566839 = 31567036
233 + 31566803 = 31567036
239 + 31566797 = 31567036
509 + 31566527 = 31567036
563 + 31566473 = 31567036
587 + 31566449 = 31567036
593 + 31566443 = 31567036

Showing the first eight; more decompositions exist.
