Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103930, here are decompositions:

11 + 103919 = 103930
17 + 103913 = 103930
41 + 103889 = 103930
89 + 103841 = 103930
227 + 103703 = 103930
311 + 103619 = 103930
317 + 103613 = 103930
347 + 103583 = 103930

Showing the first eight; more decompositions exist.
