Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28758, here are decompositions:

5 + 28753 = 28758
7 + 28751 = 28758
29 + 28729 = 28758
47 + 28711 = 28758
61 + 28697 = 28758
71 + 28687 = 28758
89 + 28669 = 28758
97 + 28661 = 28758

Showing the first eight; more decompositions exist.
