Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171040, here are decompositions:

11 + 171029 = 171040
17 + 171023 = 171040
83 + 170957 = 171040
113 + 170927 = 171040
167 + 170873 = 171040
197 + 170843 = 171040
227 + 170813 = 171040
239 + 170801 = 171040

Showing the first eight; more decompositions exist.
