Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85858, here are decompositions:

5 + 85853 = 85858
11 + 85847 = 85858
29 + 85829 = 85858
41 + 85817 = 85858
107 + 85751 = 85858
167 + 85691 = 85858
191 + 85667 = 85858
197 + 85661 = 85858

Showing the first eight; more decompositions exist.
