Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166480, here are decompositions:

23 + 166457 = 166480
71 + 166409 = 166480
131 + 166349 = 166480
179 + 166301 = 166480
191 + 166289 = 166480
233 + 166247 = 166480
311 + 166169 = 166480
449 + 166031 = 166480

Showing the first eight; more decompositions exist.
