Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28710, here are decompositions:

7 + 28703 = 28710
13 + 28697 = 28710
23 + 28687 = 28710
41 + 28669 = 28710
47 + 28663 = 28710
53 + 28657 = 28710
61 + 28649 = 28710
67 + 28643 = 28710

Showing the first eight; more decompositions exist.
