Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66172, here are decompositions:

3 + 66169 = 66172
11 + 66161 = 66172
83 + 66089 = 66172
89 + 66083 = 66172
101 + 66071 = 66172
131 + 66041 = 66172
179 + 65993 = 66172
191 + 65981 = 66172

Showing the first eight; more decompositions exist.
