Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568284, here are decompositions:

3 + 31568281 = 31568284
17 + 31568267 = 31568284
197 + 31568087 = 31568284
257 + 31568027 = 31568284
263 + 31568021 = 31568284
353 + 31567931 = 31568284
401 + 31567883 = 31568284
641 + 31567643 = 31568284

Showing the first eight; more decompositions exist.
