Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85480, here are decompositions:

11 + 85469 = 85480
29 + 85451 = 85480
41 + 85439 = 85480
53 + 85427 = 85480
149 + 85331 = 85480
167 + 85313 = 85480
233 + 85247 = 85480
251 + 85229 = 85480

Showing the first eight; more decompositions exist.
