Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85966, here are decompositions:

113 + 85853 = 85966
137 + 85829 = 85966
149 + 85817 = 85966
173 + 85793 = 85966
233 + 85733 = 85966
263 + 85703 = 85966
347 + 85619 = 85966
359 + 85607 = 85966

Showing the first eight; more decompositions exist.
