Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540568, here are decompositions:

11 + 540557 = 540568
29 + 540539 = 540568
59 + 540509 = 540568
107 + 540461 = 540568
131 + 540437 = 540568
179 + 540389 = 540568
191 + 540377 = 540568
317 + 540251 = 540568

Showing the first eight; more decompositions exist.
