Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171222, here are decompositions:

19 + 171203 = 171222
43 + 171179 = 171222
53 + 171169 = 171222
59 + 171163 = 171222
61 + 171161 = 171222
131 + 171091 = 171222
173 + 171049 = 171222
179 + 171043 = 171222

Showing the first eight; more decompositions exist.
