Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85312, here are decompositions:

53 + 85259 = 85312
83 + 85229 = 85312
89 + 85223 = 85312
113 + 85199 = 85312
179 + 85133 = 85312
191 + 85121 = 85312
251 + 85061 = 85312
263 + 85049 = 85312

Showing the first eight; more decompositions exist.
