Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28684, here are decompositions:

23 + 28661 = 28684
41 + 28643 = 28684
53 + 28631 = 28684
113 + 28571 = 28684
137 + 28547 = 28684
167 + 28517 = 28684
191 + 28493 = 28684
251 + 28433 = 28684

Showing the first eight; more decompositions exist.
