Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536046, here are decompositions:

29 + 31536017 = 31536046
107 + 31535939 = 31536046
137 + 31535909 = 31536046
167 + 31535879 = 31536046
293 + 31535753 = 31536046
389 + 31535657 = 31536046
617 + 31535429 = 31536046
719 + 31535327 = 31536046

Showing the first eight; more decompositions exist.
