Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536946, here are decompositions:

3 + 31536943 = 31536946
29 + 31536917 = 31536946
83 + 31536863 = 31536946
173 + 31536773 = 31536946
227 + 31536719 = 31536946
239 + 31536707 = 31536946
317 + 31536629 = 31536946
563 + 31536383 = 31536946

Showing the first eight; more decompositions exist.
