Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104986, here are decompositions:

53 + 104933 = 104986
107 + 104879 = 104986
137 + 104849 = 104986
197 + 104789 = 104986
227 + 104759 = 104986
257 + 104729 = 104986
263 + 104723 = 104986
269 + 104717 = 104986

Showing the first eight; more decompositions exist.
