Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66512, here are decompositions:

3 + 66509 = 66512
13 + 66499 = 66512
109 + 66403 = 66512
139 + 66373 = 66512
151 + 66361 = 66512
211 + 66301 = 66512
241 + 66271 = 66512
409 + 66103 = 66512

Showing the first eight; more decompositions exist.
