Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3172, here are decompositions:

3 + 3169 = 3172
5 + 3167 = 3172
53 + 3119 = 3172
83 + 3089 = 3172
89 + 3083 = 3172
131 + 3041 = 3172
149 + 3023 = 3172
173 + 2999 = 3172

Showing the first eight; more decompositions exist.
