Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170272, here are decompositions:

5 + 170267 = 170272
23 + 170249 = 170272
29 + 170243 = 170272
41 + 170231 = 170272
59 + 170213 = 170272
83 + 170189 = 170272
131 + 170141 = 170272
149 + 170123 = 170272

Showing the first eight; more decompositions exist.
