Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536806, here are decompositions:

13 + 31536793 = 31536806
73 + 31536733 = 31536806
109 + 31536697 = 31536806
193 + 31536613 = 31536806
199 + 31536607 = 31536806
277 + 31536529 = 31536806
307 + 31536499 = 31536806
409 + 31536397 = 31536806

Showing the first eight; more decompositions exist.
