Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104272, here are decompositions:

29 + 104243 = 104272
41 + 104231 = 104272
89 + 104183 = 104272
149 + 104123 = 104272
239 + 104033 = 104272
251 + 104021 = 104272
263 + 104009 = 104272
269 + 104003 = 104272

Showing the first eight; more decompositions exist.
