Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66312, here are decompositions:

11 + 66301 = 66312
19 + 66293 = 66312
41 + 66271 = 66312
73 + 66239 = 66312
139 + 66173 = 66312
151 + 66161 = 66312
223 + 66089 = 66312
229 + 66083 = 66312

Showing the first eight; more decompositions exist.
