Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28648, here are decompositions:

5 + 28643 = 28648
17 + 28631 = 28648
29 + 28619 = 28648
41 + 28607 = 28648
89 + 28559 = 28648
101 + 28547 = 28648
107 + 28541 = 28648
131 + 28517 = 28648

Showing the first eight; more decompositions exist.
