Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489658, here are decompositions:

5 + 489653 = 489658
101 + 489557 = 489658
107 + 489551 = 489658
179 + 489479 = 489658
227 + 489431 = 489658
251 + 489407 = 489658
269 + 489389 = 489658
359 + 489299 = 489658

Showing the first eight; more decompositions exist.
