Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536510, here are decompositions:

11 + 31536499 = 31536510
29 + 31536481 = 31536510
107 + 31536403 = 31536510
113 + 31536397 = 31536510
127 + 31536383 = 31536510
149 + 31536361 = 31536510
151 + 31536359 = 31536510
157 + 31536353 = 31536510

Showing the first eight; more decompositions exist.
