Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66546, here are decompositions:

5 + 66541 = 66546
13 + 66533 = 66546
17 + 66529 = 66546
23 + 66523 = 66546
37 + 66509 = 66546
47 + 66499 = 66546
79 + 66467 = 66546
83 + 66463 = 66546

Showing the first eight; more decompositions exist.
