Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536630, here are decompositions:

17 + 31536613 = 31536630
23 + 31536607 = 31536630
79 + 31536551 = 31536630
101 + 31536529 = 31536630
109 + 31536521 = 31536630
131 + 31536499 = 31536630
149 + 31536481 = 31536630
227 + 31536403 = 31536630

Showing the first eight; more decompositions exist.
