Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104858, here are decompositions:

7 + 104851 = 104858
31 + 104827 = 104858
79 + 104779 = 104858
97 + 104761 = 104858
151 + 104707 = 104858
157 + 104701 = 104858
181 + 104677 = 104858
199 + 104659 = 104858

Showing the first eight; more decompositions exist.
