Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489144, here are decompositions:

11 + 489133 = 489144
17 + 489127 = 489144
31 + 489113 = 489144
43 + 489101 = 489144
83 + 489061 = 489144
101 + 489043 = 489144
151 + 488993 = 489144
163 + 488981 = 489144

Showing the first eight; more decompositions exist.
