Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28760, here are decompositions:

7 + 28753 = 28760
31 + 28729 = 28760
37 + 28723 = 28760
73 + 28687 = 28760
97 + 28663 = 28760
103 + 28657 = 28760
139 + 28621 = 28760
157 + 28603 = 28760

Showing the first eight; more decompositions exist.
