Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104240, here are decompositions:

7 + 104233 = 104240
61 + 104179 = 104240
67 + 104173 = 104240
79 + 104161 = 104240
127 + 104113 = 104240
151 + 104089 = 104240
181 + 104059 = 104240
193 + 104047 = 104240

Showing the first eight; more decompositions exist.
