Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103904, here are decompositions:

37 + 103867 = 103904
61 + 103843 = 103904
67 + 103837 = 103904
103 + 103801 = 103904
181 + 103723 = 103904
223 + 103681 = 103904
313 + 103591 = 103904
331 + 103573 = 103904

Showing the first eight; more decompositions exist.
