Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66008, here are decompositions:

79 + 65929 = 66008
109 + 65899 = 66008
127 + 65881 = 66008
157 + 65851 = 66008
181 + 65827 = 66008
199 + 65809 = 66008
277 + 65731 = 66008
307 + 65701 = 66008

Showing the first eight; more decompositions exist.
