Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104790, here are decompositions:

11 + 104779 = 104790
17 + 104773 = 104790
29 + 104761 = 104790
31 + 104759 = 104790
47 + 104743 = 104790
61 + 104729 = 104790
67 + 104723 = 104790
73 + 104717 = 104790

Showing the first eight; more decompositions exist.
