Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170320, here are decompositions:

41 + 170279 = 170320
53 + 170267 = 170320
71 + 170249 = 170320
89 + 170231 = 170320
107 + 170213 = 170320
113 + 170207 = 170320
131 + 170189 = 170320
179 + 170141 = 170320

Showing the first eight; more decompositions exist.
