Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85456, here are decompositions:

3 + 85453 = 85456
5 + 85451 = 85456
17 + 85439 = 85456
29 + 85427 = 85456
197 + 85259 = 85456
227 + 85229 = 85456
233 + 85223 = 85456
257 + 85199 = 85456

Showing the first eight; more decompositions exist.
