Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536826, here are decompositions:

3 + 31536823 = 31536826
5 + 31536821 = 31536826
53 + 31536773 = 31536826
107 + 31536719 = 31536826
197 + 31536629 = 31536826
443 + 31536383 = 31536826
467 + 31536359 = 31536826
479 + 31536347 = 31536826

Showing the first eight; more decompositions exist.
