Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51284, here are decompositions:

43 + 51241 = 51284
67 + 51217 = 51284
127 + 51157 = 51284
151 + 51133 = 51284
223 + 51061 = 51284
241 + 51043 = 51284
283 + 51001 = 51284
313 + 50971 = 51284

Showing the first eight; more decompositions exist.
