Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489518, here are decompositions:

31 + 489487 = 489518
61 + 489457 = 489518
79 + 489439 = 489518
109 + 489409 = 489518
151 + 489367 = 489518
157 + 489361 = 489518
181 + 489337 = 489518
277 + 489241 = 489518

Showing the first eight; more decompositions exist.
