Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169288, here are decompositions:

5 + 169283 = 169288
29 + 169259 = 169288
47 + 169241 = 169288
71 + 169217 = 169288
89 + 169199 = 169288
107 + 169181 = 169288
137 + 169151 = 169288
191 + 169097 = 169288

Showing the first eight; more decompositions exist.
