Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85186, here are decompositions:

53 + 85133 = 85186
83 + 85103 = 85186
137 + 85049 = 85186
149 + 85037 = 85186
239 + 84947 = 85186
317 + 84869 = 85186
359 + 84827 = 85186
449 + 84737 = 85186

Showing the first eight; more decompositions exist.
