Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489284, here are decompositions:

43 + 489241 = 489284
67 + 489217 = 489284
127 + 489157 = 489284
151 + 489133 = 489284
157 + 489127 = 489284
223 + 489061 = 489284
241 + 489043 = 489284
283 + 489001 = 489284

Showing the first eight; more decompositions exist.
