Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66188, here are decompositions:

19 + 66169 = 66188
79 + 66109 = 66188
151 + 66037 = 66188
307 + 65881 = 66188
337 + 65851 = 66188
349 + 65839 = 66188
379 + 65809 = 66188
457 + 65731 = 66188

Showing the first eight; more decompositions exist.
