Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28284, here are decompositions:

5 + 28279 = 28284
7 + 28277 = 28284
73 + 28211 = 28284
83 + 28201 = 28284
101 + 28183 = 28284
103 + 28181 = 28284
173 + 28111 = 28284
197 + 28087 = 28284

Showing the first eight; more decompositions exist.
