Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536256, here are decompositions:

29 + 31536227 = 31536256
53 + 31536203 = 31536256
239 + 31536017 = 31536256
317 + 31535939 = 31536256
347 + 31535909 = 31536256
503 + 31535753 = 31536256
509 + 31535747 = 31536256
599 + 31535657 = 31536256

Showing the first eight; more decompositions exist.
