Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536252, here are decompositions:

29 + 31536223 = 31536252
151 + 31536101 = 31536252
191 + 31536061 = 31536252
199 + 31536053 = 31536252
233 + 31536019 = 31536252
269 + 31535983 = 31536252
271 + 31535981 = 31536252
311 + 31535941 = 31536252

Showing the first eight; more decompositions exist.
