Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103908, here are decompositions:

5 + 103903 = 103908
19 + 103889 = 103908
41 + 103867 = 103908
67 + 103841 = 103908
71 + 103837 = 103908
97 + 103811 = 103908
107 + 103801 = 103908
139 + 103769 = 103908

Showing the first eight; more decompositions exist.
