Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534966, here are decompositions:

5 + 31534961 = 31534966
53 + 31534913 = 31534966
167 + 31534799 = 31534966
179 + 31534787 = 31534966
227 + 31534739 = 31534966
257 + 31534709 = 31534966
479 + 31534487 = 31534966
509 + 31534457 = 31534966

Showing the first eight; more decompositions exist.
