Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28732, here are decompositions:

3 + 28729 = 28732
29 + 28703 = 28732
71 + 28661 = 28732
83 + 28649 = 28732
89 + 28643 = 28732
101 + 28631 = 28732
113 + 28619 = 28732
173 + 28559 = 28732

Showing the first eight; more decompositions exist.
