Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489220, here are decompositions:

3 + 489217 = 489220
23 + 489197 = 489220
29 + 489191 = 489220
41 + 489179 = 489220
59 + 489161 = 489220
107 + 489113 = 489220
167 + 489053 = 489220
227 + 488993 = 489220

Showing the first eight; more decompositions exist.
