Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85286, here are decompositions:

43 + 85243 = 85286
73 + 85213 = 85286
127 + 85159 = 85286
139 + 85147 = 85286
193 + 85093 = 85286
199 + 85087 = 85286
277 + 85009 = 85286
307 + 84979 = 85286

Showing the first eight; more decompositions exist.
