Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104166, here are decompositions:

5 + 104161 = 104166
17 + 104149 = 104166
19 + 104147 = 104166
43 + 104123 = 104166
47 + 104119 = 104166
53 + 104113 = 104166
59 + 104107 = 104166
79 + 104087 = 104166

Showing the first eight; more decompositions exist.
