Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104242, here are decompositions:

3 + 104239 = 104242
11 + 104231 = 104242
59 + 104183 = 104242
233 + 104009 = 104242
239 + 104003 = 104242
251 + 103991 = 104242
263 + 103979 = 104242
353 + 103889 = 104242

Showing the first eight; more decompositions exist.
