Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15172, here are decompositions:

11 + 15161 = 15172
23 + 15149 = 15172
41 + 15131 = 15172
71 + 15101 = 15172
89 + 15083 = 15172
233 + 14939 = 15172
281 + 14891 = 15172
293 + 14879 = 15172

Showing the first eight; more decompositions exist.
