Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169564, here are decompositions:

11 + 169553 = 169564
41 + 169523 = 169564
71 + 169493 = 169564
107 + 169457 = 169564
137 + 169427 = 169564
191 + 169373 = 169564
251 + 169313 = 169564
257 + 169307 = 169564

Showing the first eight; more decompositions exist.
