Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 56730, here are decompositions:

17 + 56713 = 56730
19 + 56711 = 56730
29 + 56701 = 56730
43 + 56687 = 56730
59 + 56671 = 56730
67 + 56663 = 56730
71 + 56659 = 56730
97 + 56633 = 56730

Showing the first eight; more decompositions exist.
