Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489408, here are decompositions:

19 + 489389 = 489408
41 + 489367 = 489408
47 + 489361 = 489408
71 + 489337 = 489408
79 + 489329 = 489408
109 + 489299 = 489408
151 + 489257 = 489408
167 + 489241 = 489408

Showing the first eight; more decompositions exist.
