Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68730, here are decompositions:

17 + 68713 = 68730
19 + 68711 = 68730
31 + 68699 = 68730
43 + 68687 = 68730
47 + 68683 = 68730
61 + 68669 = 68730
71 + 68659 = 68730
97 + 68633 = 68730

Showing the first eight; more decompositions exist.
