Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28750, here are decompositions:

47 + 28703 = 28750
53 + 28697 = 28750
89 + 28661 = 28750
101 + 28649 = 28750
107 + 28643 = 28750
131 + 28619 = 28750
179 + 28571 = 28750
191 + 28559 = 28750

Showing the first eight; more decompositions exist.
