Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489172, here are decompositions:

11 + 489161 = 489172
59 + 489113 = 489172
71 + 489101 = 489172
179 + 488993 = 489172
191 + 488981 = 489172
251 + 488921 = 489172
263 + 488909 = 489172
293 + 488879 = 489172

Showing the first eight; more decompositions exist.
