Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85270, here are decompositions:

11 + 85259 = 85270
23 + 85247 = 85270
41 + 85229 = 85270
47 + 85223 = 85270
71 + 85199 = 85270
137 + 85133 = 85270
149 + 85121 = 85270
167 + 85103 = 85270

Showing the first eight; more decompositions exist.
