Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536708, here are decompositions:

11 + 31536697 = 31536708
79 + 31536629 = 31536708
101 + 31536607 = 31536708
157 + 31536551 = 31536708
179 + 31536529 = 31536708
227 + 31536481 = 31536708
311 + 31536397 = 31536708
317 + 31536391 = 31536708

Showing the first eight; more decompositions exist.
