Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12172, here are decompositions:

11 + 12161 = 12172
23 + 12149 = 12172
29 + 12143 = 12172
53 + 12119 = 12172
59 + 12113 = 12172
71 + 12101 = 12172
101 + 12071 = 12172
131 + 12041 = 12172

Showing the first eight; more decompositions exist.
