Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489472, here are decompositions:

23 + 489449 = 489472
41 + 489431 = 489472
83 + 489389 = 489472
173 + 489299 = 489472
233 + 489239 = 489472
281 + 489191 = 489472
293 + 489179 = 489472
311 + 489161 = 489472

Showing the first eight; more decompositions exist.
