Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489802, here are decompositions:

3 + 489799 = 489802
11 + 489791 = 489802
41 + 489761 = 489802
59 + 489743 = 489802
113 + 489689 = 489802
149 + 489653 = 489802
251 + 489551 = 489802
263 + 489539 = 489802

Showing the first eight; more decompositions exist.
