Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489142, here are decompositions:

29 + 489113 = 489142
41 + 489101 = 489142
89 + 489053 = 489142
131 + 489011 = 489142
149 + 488993 = 489142
233 + 488909 = 489142
263 + 488879 = 489142
281 + 488861 = 489142

Showing the first eight; more decompositions exist.
