Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489668, here are decompositions:

37 + 489631 = 489668
97 + 489571 = 489668
139 + 489529 = 489668
181 + 489487 = 489668
211 + 489457 = 489668
229 + 489439 = 489668
241 + 489427 = 489668
307 + 489361 = 489668

Showing the first eight; more decompositions exist.
