Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489238, here are decompositions:

41 + 489197 = 489238
47 + 489191 = 489238
59 + 489179 = 489238
137 + 489101 = 489238
227 + 489011 = 489238
257 + 488981 = 489238
317 + 488921 = 489238
359 + 488879 = 489238

Showing the first eight; more decompositions exist.
