Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85104, here are decompositions:

11 + 85093 = 85104
13 + 85091 = 85104
17 + 85087 = 85104
23 + 85081 = 85104
43 + 85061 = 85104
67 + 85037 = 85104
83 + 85021 = 85104
113 + 84991 = 85104

Showing the first eight; more decompositions exist.
