Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66210, here are decompositions:

19 + 66191 = 66210
31 + 66179 = 66210
37 + 66173 = 66210
41 + 66169 = 66210
73 + 66137 = 66210
101 + 66109 = 66210
103 + 66107 = 66210
107 + 66103 = 66210

Showing the first eight; more decompositions exist.
