Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536726, here are decompositions:

7 + 31536719 = 31536726
19 + 31536707 = 31536726
29 + 31536697 = 31536726
97 + 31536629 = 31536726
113 + 31536613 = 31536726
197 + 31536529 = 31536726
227 + 31536499 = 31536726
367 + 31536359 = 31536726

Showing the first eight; more decompositions exist.
