Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103986, here are decompositions:

5 + 103981 = 103986
7 + 103979 = 103986
17 + 103969 = 103986
19 + 103967 = 103986
23 + 103963 = 103986
67 + 103919 = 103986
73 + 103913 = 103986
83 + 103903 = 103986

Showing the first eight; more decompositions exist.
