Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103998, here are decompositions:

5 + 103993 = 103998
7 + 103991 = 103998
17 + 103981 = 103998
19 + 103979 = 103998
29 + 103969 = 103998
31 + 103967 = 103998
47 + 103951 = 103998
79 + 103919 = 103998

Showing the first eight; more decompositions exist.
