Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28792, here are decompositions:

3 + 28789 = 28792
41 + 28751 = 28792
89 + 28703 = 28792
131 + 28661 = 28792
149 + 28643 = 28792
173 + 28619 = 28792
233 + 28559 = 28792
251 + 28541 = 28792

Showing the first eight; more decompositions exist.
