Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 63666, here are decompositions:

7 + 63659 = 63666
17 + 63649 = 63666
19 + 63647 = 63666
37 + 63629 = 63666
59 + 63607 = 63666
67 + 63599 = 63666
79 + 63587 = 63666
89 + 63577 = 63666

Showing the first eight; more decompositions exist.
