Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85170, here are decompositions:

11 + 85159 = 85170
23 + 85147 = 85170
37 + 85133 = 85170
61 + 85109 = 85170
67 + 85103 = 85170
79 + 85091 = 85170
83 + 85087 = 85170
89 + 85081 = 85170

Showing the first eight; more decompositions exist.
