Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489670, here are decompositions:

11 + 489659 = 489670
17 + 489653 = 489670
113 + 489557 = 489670
131 + 489539 = 489670
191 + 489479 = 489670
239 + 489431 = 489670
263 + 489407 = 489670
281 + 489389 = 489670

Showing the first eight; more decompositions exist.
