Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568262, here are decompositions:

41 + 31568221 = 31568262
59 + 31568203 = 31568262
83 + 31568179 = 31568262
139 + 31568123 = 31568262
179 + 31568083 = 31568262
191 + 31568071 = 31568262
241 + 31568021 = 31568262
263 + 31567999 = 31568262

Showing the first eight; more decompositions exist.
