Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66408, here are decompositions:

5 + 66403 = 66408
31 + 66377 = 66408
47 + 66361 = 66408
61 + 66347 = 66408
71 + 66337 = 66408
107 + 66301 = 66408
137 + 66271 = 66408
229 + 66179 = 66408

Showing the first eight; more decompositions exist.
