Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85306, here are decompositions:

3 + 85303 = 85306
47 + 85259 = 85306
59 + 85247 = 85306
83 + 85223 = 85306
107 + 85199 = 85306
113 + 85193 = 85306
173 + 85133 = 85306
197 + 85109 = 85306

Showing the first eight; more decompositions exist.
