Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85210, here are decompositions:

11 + 85199 = 85210
17 + 85193 = 85210
89 + 85121 = 85210
101 + 85109 = 85210
107 + 85103 = 85210
149 + 85061 = 85210
173 + 85037 = 85210
233 + 84977 = 85210

Showing the first eight; more decompositions exist.
