Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104918, here are decompositions:

7 + 104911 = 104918
67 + 104851 = 104918
139 + 104779 = 104918
157 + 104761 = 104918
211 + 104707 = 104918
241 + 104677 = 104918
367 + 104551 = 104918
439 + 104479 = 104918

Showing the first eight; more decompositions exist.
