Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42568, here are decompositions:

11 + 42557 = 42568
59 + 42509 = 42568
101 + 42467 = 42568
107 + 42461 = 42568
131 + 42437 = 42568
269 + 42299 = 42568
311 + 42257 = 42568
347 + 42221 = 42568

Showing the first eight; more decompositions exist.
