Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489272, here are decompositions:

31 + 489241 = 489272
139 + 489133 = 489272
163 + 489109 = 489272
211 + 489061 = 489272
229 + 489043 = 489272
271 + 489001 = 489272
313 + 488959 = 489272
379 + 488893 = 489272

Showing the first eight; more decompositions exist.
