Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489442, here are decompositions:

3 + 489439 = 489442
11 + 489431 = 489442
53 + 489389 = 489442
113 + 489329 = 489442
179 + 489263 = 489442
251 + 489191 = 489442
263 + 489179 = 489442
281 + 489161 = 489442

Showing the first eight; more decompositions exist.
