Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64066, here are decompositions:

3 + 64063 = 64066
29 + 64037 = 64066
47 + 64019 = 64066
53 + 64013 = 64066
59 + 64007 = 64066
89 + 63977 = 64066
137 + 63929 = 64066
227 + 63839 = 64066

Showing the first eight; more decompositions exist.
