Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489398, here are decompositions:

31 + 489367 = 489398
37 + 489361 = 489398
61 + 489337 = 489398
157 + 489241 = 489398
181 + 489217 = 489398
241 + 489157 = 489398
271 + 489127 = 489398
337 + 489061 = 489398

Showing the first eight; more decompositions exist.
