Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28770, here are decompositions:

11 + 28759 = 28770
17 + 28753 = 28770
19 + 28751 = 28770
41 + 28729 = 28770
47 + 28723 = 28770
59 + 28711 = 28770
67 + 28703 = 28770
73 + 28697 = 28770

Showing the first eight; more decompositions exist.
