Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66608, here are decompositions:

7 + 66601 = 66608
37 + 66571 = 66608
67 + 66541 = 66608
79 + 66529 = 66608
109 + 66499 = 66608
151 + 66457 = 66608
271 + 66337 = 66608
307 + 66301 = 66608

Showing the first eight; more decompositions exist.
