Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104128, here are decompositions:

5 + 104123 = 104128
41 + 104087 = 104128
107 + 104021 = 104128
131 + 103997 = 104128
137 + 103991 = 104128
149 + 103979 = 104128
239 + 103889 = 104128
317 + 103811 = 104128

Showing the first eight; more decompositions exist.
