Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28736, here are decompositions:

7 + 28729 = 28736
13 + 28723 = 28736
67 + 28669 = 28736
73 + 28663 = 28736
79 + 28657 = 28736
109 + 28627 = 28736
139 + 28597 = 28736
157 + 28579 = 28736

Showing the first eight; more decompositions exist.
