Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103938, here are decompositions:

19 + 103919 = 103938
71 + 103867 = 103938
97 + 103841 = 103938
101 + 103837 = 103938
127 + 103811 = 103938
137 + 103801 = 103938
151 + 103787 = 103938
239 + 103699 = 103938

Showing the first eight; more decompositions exist.
