Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66826, here are decompositions:

5 + 66821 = 66826
17 + 66809 = 66826
29 + 66797 = 66826
113 + 66713 = 66826
173 + 66653 = 66826
197 + 66629 = 66826
233 + 66593 = 66826
239 + 66587 = 66826

Showing the first eight; more decompositions exist.
