Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111930, here are decompositions:

11 + 111919 = 111930
17 + 111913 = 111930
37 + 111893 = 111930
59 + 111871 = 111930
61 + 111869 = 111930
67 + 111863 = 111930
73 + 111857 = 111930
83 + 111847 = 111930

Showing the first eight; more decompositions exist.
