Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104724, here are decompositions:

7 + 104717 = 104724
13 + 104711 = 104724
17 + 104707 = 104724
23 + 104701 = 104724
31 + 104693 = 104724
41 + 104683 = 104724
43 + 104681 = 104724
47 + 104677 = 104724

Showing the first eight; more decompositions exist.
