Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104290, here are decompositions:

3 + 104287 = 104290
47 + 104243 = 104290
59 + 104231 = 104290
83 + 104207 = 104290
107 + 104183 = 104290
167 + 104123 = 104290
257 + 104033 = 104290
269 + 104021 = 104290

Showing the first eight; more decompositions exist.
