Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102858, here are decompositions:

17 + 102841 = 102858
29 + 102829 = 102858
47 + 102811 = 102858
61 + 102797 = 102858
89 + 102769 = 102858
97 + 102761 = 102858
157 + 102701 = 102858
179 + 102679 = 102858

Showing the first eight; more decompositions exist.
