Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85288, here are decompositions:

29 + 85259 = 85288
41 + 85247 = 85288
59 + 85229 = 85288
89 + 85199 = 85288
167 + 85121 = 85288
179 + 85109 = 85288
197 + 85091 = 85288
227 + 85061 = 85288

Showing the first eight; more decompositions exist.
