Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42586, here are decompositions:

17 + 42569 = 42586
29 + 42557 = 42586
53 + 42533 = 42586
113 + 42473 = 42586
149 + 42437 = 42586
179 + 42407 = 42586
227 + 42359 = 42586
263 + 42323 = 42586

Showing the first eight; more decompositions exist.
