Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85686, here are decompositions:

17 + 85669 = 85686
19 + 85667 = 85686
43 + 85643 = 85686
47 + 85639 = 85686
59 + 85627 = 85686
67 + 85619 = 85686
79 + 85607 = 85686
89 + 85597 = 85686

Showing the first eight; more decompositions exist.
