Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103866, here are decompositions:

23 + 103843 = 103866
29 + 103837 = 103866
53 + 103813 = 103866
79 + 103787 = 103866
97 + 103769 = 103866
163 + 103703 = 103866
167 + 103699 = 103866
179 + 103687 = 103866

Showing the first eight; more decompositions exist.
