Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18172, here are decompositions:

3 + 18169 = 18172
23 + 18149 = 18172
29 + 18143 = 18172
41 + 18131 = 18172
53 + 18119 = 18172
83 + 18089 = 18172
113 + 18059 = 18172
131 + 18041 = 18172

Showing the first eight; more decompositions exist.
