Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 109908, here are decompositions:

5 + 109903 = 109908
11 + 109897 = 109908
17 + 109891 = 109908
59 + 109849 = 109908
61 + 109847 = 109908
67 + 109841 = 109908
79 + 109829 = 109908
89 + 109819 = 109908

Showing the first eight; more decompositions exist.
