Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559304, here are decompositions:

41 + 31559263 = 31559304
53 + 31559251 = 31559304
97 + 31559207 = 31559304
173 + 31559131 = 31559304
211 + 31559093 = 31559304
223 + 31559081 = 31559304
233 + 31559071 = 31559304
277 + 31559027 = 31559304

Showing the first eight; more decompositions exist.
