Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489444, here are decompositions:

5 + 489439 = 489444
13 + 489431 = 489444
17 + 489427 = 489444
37 + 489407 = 489444
83 + 489361 = 489444
101 + 489343 = 489444
107 + 489337 = 489444
181 + 489263 = 489444

Showing the first eight; more decompositions exist.
