Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66586, here are decompositions:

17 + 66569 = 66586
53 + 66533 = 66586
137 + 66449 = 66586
173 + 66413 = 66586
227 + 66359 = 66586
239 + 66347 = 66586
293 + 66293 = 66586
347 + 66239 = 66586

Showing the first eight; more decompositions exist.
