Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85228, here are decompositions:

5 + 85223 = 85228
29 + 85199 = 85228
107 + 85121 = 85228
137 + 85091 = 85228
167 + 85061 = 85228
179 + 85049 = 85228
191 + 85037 = 85228
251 + 84977 = 85228

Showing the first eight; more decompositions exist.
