Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489650, here are decompositions:

19 + 489631 = 489650
37 + 489613 = 489650
79 + 489571 = 489650
97 + 489553 = 489650
157 + 489493 = 489650
163 + 489487 = 489650
193 + 489457 = 489650
211 + 489439 = 489650

Showing the first eight; more decompositions exist.
