Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171226, here are decompositions:

23 + 171203 = 171226
47 + 171179 = 171226
59 + 171167 = 171226
149 + 171077 = 171226
173 + 171053 = 171226
179 + 171047 = 171226
197 + 171029 = 171226
269 + 170957 = 171226

Showing the first eight; more decompositions exist.
