Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568674, here are decompositions:

17 + 31568657 = 31568674
113 + 31568561 = 31568674
131 + 31568543 = 31568674
251 + 31568423 = 31568674
257 + 31568417 = 31568674
281 + 31568393 = 31568674
317 + 31568357 = 31568674
587 + 31568087 = 31568674

Showing the first eight; more decompositions exist.
