Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489772, here are decompositions:

11 + 489761 = 489772
29 + 489743 = 489772
83 + 489689 = 489772
113 + 489659 = 489772
233 + 489539 = 489772
293 + 489479 = 489772
383 + 489389 = 489772
443 + 489329 = 489772

Showing the first eight; more decompositions exist.
