Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66464, here are decompositions:

7 + 66457 = 66464
61 + 66403 = 66464
103 + 66361 = 66464
127 + 66337 = 66464
163 + 66301 = 66464
193 + 66271 = 66464
397 + 66067 = 66464
613 + 65851 = 66464

Showing the first eight; more decompositions exist.
