Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169540, here are decompositions:

17 + 169523 = 169540
47 + 169493 = 169540
83 + 169457 = 169540
113 + 169427 = 169540
131 + 169409 = 169540
167 + 169373 = 169540
179 + 169361 = 169540
197 + 169343 = 169540

Showing the first eight; more decompositions exist.
