Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489502, here are decompositions:

23 + 489479 = 489502
53 + 489449 = 489502
71 + 489431 = 489502
113 + 489389 = 489502
173 + 489329 = 489502
239 + 489263 = 489502
263 + 489239 = 489502
311 + 489191 = 489502

Showing the first eight; more decompositions exist.
