Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536786, here are decompositions:

13 + 31536773 = 31536786
53 + 31536733 = 31536786
67 + 31536719 = 31536786
79 + 31536707 = 31536786
89 + 31536697 = 31536786
157 + 31536629 = 31536786
173 + 31536613 = 31536786
179 + 31536607 = 31536786

Showing the first eight; more decompositions exist.
