Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104820, here are decompositions:

17 + 104803 = 104820
19 + 104801 = 104820
31 + 104789 = 104820
41 + 104779 = 104820
47 + 104773 = 104820
59 + 104761 = 104820
61 + 104759 = 104820
97 + 104723 = 104820

Showing the first eight; more decompositions exist.
