Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28788, here are decompositions:

17 + 28771 = 28788
29 + 28759 = 28788
37 + 28751 = 28788
59 + 28729 = 28788
101 + 28687 = 28788
127 + 28661 = 28788
131 + 28657 = 28788
139 + 28649 = 28788

Showing the first eight; more decompositions exist.
