Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15178, here are decompositions:

5 + 15173 = 15178
17 + 15161 = 15178
29 + 15149 = 15178
41 + 15137 = 15178
47 + 15131 = 15178
71 + 15107 = 15178
101 + 15077 = 15178
227 + 14951 = 15178

Showing the first eight; more decompositions exist.
