Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66766, here are decompositions:

3 + 66763 = 66766
17 + 66749 = 66766
53 + 66713 = 66766
83 + 66683 = 66766
113 + 66653 = 66766
137 + 66629 = 66766
149 + 66617 = 66766
173 + 66593 = 66766

Showing the first eight; more decompositions exist.
