Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568444, here are decompositions:

31 + 31568413 = 31568444
97 + 31568347 = 31568444
157 + 31568287 = 31568444
163 + 31568281 = 31568444
223 + 31568221 = 31568444
241 + 31568203 = 31568444
337 + 31568107 = 31568444
373 + 31568071 = 31568444

Showing the first eight; more decompositions exist.
