Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169480, here are decompositions:

23 + 169457 = 169480
53 + 169427 = 169480
71 + 169409 = 169480
107 + 169373 = 169480
137 + 169343 = 169480
167 + 169313 = 169480
173 + 169307 = 169480
197 + 169283 = 169480

Showing the first eight; more decompositions exist.
