Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103988, here are decompositions:

7 + 103981 = 103988
19 + 103969 = 103988
37 + 103951 = 103988
151 + 103837 = 103988
307 + 103681 = 103988
331 + 103657 = 103988
337 + 103651 = 103988
397 + 103591 = 103988

Showing the first eight; more decompositions exist.
