Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143568, here are decompositions:

17 + 143551 = 143568
31 + 143537 = 143568
41 + 143527 = 143568
59 + 143509 = 143568
67 + 143501 = 143568
79 + 143489 = 143568
101 + 143467 = 143568
107 + 143461 = 143568

Showing the first eight; more decompositions exist.
