Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103886, here are decompositions:

19 + 103867 = 103886
43 + 103843 = 103886
73 + 103813 = 103886
163 + 103723 = 103886
199 + 103687 = 103886
229 + 103657 = 103886
313 + 103573 = 103886
337 + 103549 = 103886

Showing the first eight; more decompositions exist.
