Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28798, here are decompositions:

5 + 28793 = 28798
47 + 28751 = 28798
101 + 28697 = 28798
137 + 28661 = 28798
149 + 28649 = 28798
167 + 28631 = 28798
179 + 28619 = 28798
191 + 28607 = 28798

Showing the first eight; more decompositions exist.
