Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66648, here are decompositions:

5 + 66643 = 66648
19 + 66629 = 66648
31 + 66617 = 66648
47 + 66601 = 66648
61 + 66587 = 66648
79 + 66569 = 66648
107 + 66541 = 66648
139 + 66509 = 66648

Showing the first eight; more decompositions exist.
