Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28654, here are decompositions:

5 + 28649 = 28654
11 + 28643 = 28654
23 + 28631 = 28654
47 + 28607 = 28654
83 + 28571 = 28654
107 + 28547 = 28654
113 + 28541 = 28654
137 + 28517 = 28654

Showing the first eight; more decompositions exist.
