Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85400, here are decompositions:

19 + 85381 = 85400
31 + 85369 = 85400
37 + 85363 = 85400
67 + 85333 = 85400
97 + 85303 = 85400
103 + 85297 = 85400
157 + 85243 = 85400
163 + 85237 = 85400

Showing the first eight; more decompositions exist.
