Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66168, here are decompositions:

7 + 66161 = 66168
31 + 66137 = 66168
59 + 66109 = 66168
61 + 66107 = 66168
79 + 66089 = 66168
97 + 66071 = 66168
101 + 66067 = 66168
127 + 66041 = 66168

Showing the first eight; more decompositions exist.
