Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28664, here are decompositions:

3 + 28661 = 28664
7 + 28657 = 28664
37 + 28627 = 28664
43 + 28621 = 28664
61 + 28603 = 28664
67 + 28597 = 28664
73 + 28591 = 28664
127 + 28537 = 28664

Showing the first eight; more decompositions exist.
