Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66616, here are decompositions:

23 + 66593 = 66616
29 + 66587 = 66616
47 + 66569 = 66616
83 + 66533 = 66616
107 + 66509 = 66616
149 + 66467 = 66616
167 + 66449 = 66616
233 + 66383 = 66616

Showing the first eight; more decompositions exist.
