Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104158, here are decompositions:

11 + 104147 = 104158
71 + 104087 = 104158
137 + 104021 = 104158
149 + 104009 = 104158
167 + 103991 = 104158
179 + 103979 = 104158
191 + 103967 = 104158
239 + 103919 = 104158

Showing the first eight; more decompositions exist.
