Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536118, here are decompositions:

17 + 31536101 = 31536118
101 + 31536017 = 31536118
137 + 31535981 = 31536118
179 + 31535939 = 31536118
239 + 31535879 = 31536118
401 + 31535717 = 31536118
461 + 31535657 = 31536118
479 + 31535639 = 31536118

Showing the first eight; more decompositions exist.
