Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536710, here are decompositions:

3 + 31536707 = 31536710
13 + 31536697 = 31536710
97 + 31536613 = 31536710
103 + 31536607 = 31536710
181 + 31536529 = 31536710
211 + 31536499 = 31536710
229 + 31536481 = 31536710
307 + 31536403 = 31536710

Showing the first eight; more decompositions exist.
