Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85316, here are decompositions:

3 + 85313 = 85316
13 + 85303 = 85316
19 + 85297 = 85316
73 + 85243 = 85316
79 + 85237 = 85316
103 + 85213 = 85316
157 + 85159 = 85316
223 + 85093 = 85316

Showing the first eight; more decompositions exist.
