Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568652, here are decompositions:

23 + 31568629 = 31568652
41 + 31568611 = 31568652
109 + 31568543 = 31568652
113 + 31568539 = 31568652
229 + 31568423 = 31568652
233 + 31568419 = 31568652
239 + 31568413 = 31568652
431 + 31568221 = 31568652

Showing the first eight; more decompositions exist.
