Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28722, here are decompositions:

11 + 28711 = 28722
19 + 28703 = 28722
53 + 28669 = 28722
59 + 28663 = 28722
61 + 28661 = 28722
73 + 28649 = 28722
79 + 28643 = 28722
101 + 28621 = 28722

Showing the first eight; more decompositions exist.
