Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66606, here are decompositions:

5 + 66601 = 66606
13 + 66593 = 66606
19 + 66587 = 66606
37 + 66569 = 66606
53 + 66553 = 66606
73 + 66533 = 66606
83 + 66523 = 66606
97 + 66509 = 66606

Showing the first eight; more decompositions exist.
