Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85506, here are decompositions:

19 + 85487 = 85506
37 + 85469 = 85506
53 + 85453 = 85506
59 + 85447 = 85506
67 + 85439 = 85506
79 + 85427 = 85506
137 + 85369 = 85506
173 + 85333 = 85506

Showing the first eight; more decompositions exist.
