Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28734, here are decompositions:

5 + 28729 = 28734
11 + 28723 = 28734
23 + 28711 = 28734
31 + 28703 = 28734
37 + 28697 = 28734
47 + 28687 = 28734
71 + 28663 = 28734
73 + 28661 = 28734

Showing the first eight; more decompositions exist.
