Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66064, here are decompositions:

17 + 66047 = 66064
23 + 66041 = 66064
71 + 65993 = 66064
83 + 65981 = 66064
101 + 65963 = 66064
107 + 65957 = 66064
113 + 65951 = 66064
137 + 65927 = 66064

Showing the first eight; more decompositions exist.
