Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180586, here are decompositions:

17 + 180569 = 180586
23 + 180563 = 180586
47 + 180539 = 180586
53 + 180533 = 180586
83 + 180503 = 180586
89 + 180497 = 180586
113 + 180473 = 180586
149 + 180437 = 180586

Showing the first eight; more decompositions exist.
