Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66524, here are decompositions:

61 + 66463 = 66524
67 + 66457 = 66524
151 + 66373 = 66524
163 + 66361 = 66524
181 + 66343 = 66524
223 + 66301 = 66524
421 + 66103 = 66524
457 + 66067 = 66524

Showing the first eight; more decompositions exist.
