Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171228, here are decompositions:

59 + 171169 = 171228
61 + 171167 = 171228
67 + 171161 = 171228
97 + 171131 = 171228
137 + 171091 = 171228
149 + 171079 = 171228
151 + 171077 = 171228
179 + 171049 = 171228

Showing the first eight; more decompositions exist.
