Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489402, here are decompositions:

13 + 489389 = 489402
41 + 489361 = 489402
59 + 489343 = 489402
73 + 489329 = 489402
103 + 489299 = 489402
139 + 489263 = 489402
163 + 489239 = 489402
211 + 489191 = 489402

Showing the first eight; more decompositions exist.
