Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66486, here are decompositions:

19 + 66467 = 66486
23 + 66463 = 66486
29 + 66457 = 66486
37 + 66449 = 66486
73 + 66413 = 66486
83 + 66403 = 66486
103 + 66383 = 66486
109 + 66377 = 66486

Showing the first eight; more decompositions exist.
