Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28754, here are decompositions:

3 + 28751 = 28754
31 + 28723 = 28754
43 + 28711 = 28754
67 + 28687 = 28754
97 + 28657 = 28754
127 + 28627 = 28754
151 + 28603 = 28754
157 + 28597 = 28754

Showing the first eight; more decompositions exist.
