Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103816, here are decompositions:

3 + 103813 = 103816
5 + 103811 = 103816
29 + 103787 = 103816
47 + 103769 = 103816
113 + 103703 = 103816
173 + 103643 = 103816
197 + 103619 = 103816
233 + 103583 = 103816

Showing the first eight; more decompositions exist.
