Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28804, here are decompositions:

11 + 28793 = 28804
53 + 28751 = 28804
101 + 28703 = 28804
107 + 28697 = 28804
173 + 28631 = 28804
197 + 28607 = 28804
233 + 28571 = 28804
257 + 28547 = 28804

Showing the first eight; more decompositions exist.
