Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85906, here are decompositions:

3 + 85903 = 85906
17 + 85889 = 85906
53 + 85853 = 85906
59 + 85847 = 85906
89 + 85817 = 85906
113 + 85793 = 85906
173 + 85733 = 85906
239 + 85667 = 85906

Showing the first eight; more decompositions exist.
