Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66858, here are decompositions:

5 + 66853 = 66858
7 + 66851 = 66858
17 + 66841 = 66858
37 + 66821 = 66858
61 + 66797 = 66858
67 + 66791 = 66858
107 + 66751 = 66858
109 + 66749 = 66858

Showing the first eight; more decompositions exist.
