Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489252, here are decompositions:

11 + 489241 = 489252
13 + 489239 = 489252
61 + 489191 = 489252
73 + 489179 = 489252
139 + 489113 = 489252
151 + 489101 = 489252
191 + 489061 = 489252
199 + 489053 = 489252

Showing the first eight; more decompositions exist.
