Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85018, here are decompositions:

41 + 84977 = 85018
71 + 84947 = 85018
149 + 84869 = 85018
191 + 84827 = 85018
257 + 84761 = 85018
281 + 84737 = 85018
317 + 84701 = 85018
359 + 84659 = 85018

Showing the first eight; more decompositions exist.
