Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568244, here are decompositions:

17 + 31568227 = 31568244
23 + 31568221 = 31568244
41 + 31568203 = 31568244
47 + 31568197 = 31568244
137 + 31568107 = 31568244
157 + 31568087 = 31568244
173 + 31568071 = 31568244
223 + 31568021 = 31568244

Showing the first eight; more decompositions exist.
