Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28746, here are decompositions:

17 + 28729 = 28746
23 + 28723 = 28746
43 + 28703 = 28746
59 + 28687 = 28746
83 + 28663 = 28746
89 + 28657 = 28746
97 + 28649 = 28746
103 + 28643 = 28746

Showing the first eight; more decompositions exist.
