Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169284, here are decompositions:

41 + 169243 = 169284
43 + 169241 = 169284
67 + 169217 = 169284
103 + 169181 = 169284
107 + 169177 = 169284
173 + 169111 = 169284
191 + 169093 = 169284
277 + 169007 = 169284

Showing the first eight; more decompositions exist.
