Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66550, here are decompositions:

17 + 66533 = 66550
41 + 66509 = 66550
59 + 66491 = 66550
83 + 66467 = 66550
101 + 66449 = 66550
137 + 66413 = 66550
167 + 66383 = 66550
173 + 66377 = 66550

Showing the first eight; more decompositions exist.
