Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39858, here are decompositions:

11 + 39847 = 39858
17 + 39841 = 39858
19 + 39839 = 39858
29 + 39829 = 39858
31 + 39827 = 39858
37 + 39821 = 39858
59 + 39799 = 39858
67 + 39791 = 39858

Showing the first eight; more decompositions exist.
