Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169186, here are decompositions:

5 + 169181 = 169186
89 + 169097 = 169186
107 + 169079 = 169186
137 + 169049 = 169186
167 + 169019 = 169186
179 + 169007 = 169186
293 + 168893 = 169186
317 + 168869 = 169186

Showing the first eight; more decompositions exist.
