Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489494, here are decompositions:

7 + 489487 = 489494
37 + 489457 = 489494
67 + 489427 = 489494
127 + 489367 = 489494
151 + 489343 = 489494
157 + 489337 = 489494
211 + 489283 = 489494
277 + 489217 = 489494

Showing the first eight; more decompositions exist.
