Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64666, here are decompositions:

3 + 64663 = 64666
5 + 64661 = 64666
53 + 64613 = 64666
89 + 64577 = 64666
113 + 64553 = 64666
167 + 64499 = 64666
227 + 64439 = 64666
233 + 64433 = 64666

Showing the first eight; more decompositions exist.
