Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560016, here are decompositions:

167 + 31559849 = 31560016
233 + 31559783 = 31560016
239 + 31559777 = 31560016
317 + 31559699 = 31560016
443 + 31559573 = 31560016
479 + 31559537 = 31560016
569 + 31559447 = 31560016
599 + 31559417 = 31560016

Showing the first eight; more decompositions exist.
