Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536810, here are decompositions:

17 + 31536793 = 31536810
37 + 31536773 = 31536810
79 + 31536731 = 31536810
103 + 31536707 = 31536810
113 + 31536697 = 31536810
181 + 31536629 = 31536810
197 + 31536613 = 31536810
271 + 31536539 = 31536810

Showing the first eight; more decompositions exist.
