Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489866, here are decompositions:

19 + 489847 = 489866
43 + 489823 = 489866
67 + 489799 = 489866
73 + 489793 = 489866
193 + 489673 = 489866
313 + 489553 = 489866
337 + 489529 = 489866
373 + 489493 = 489866

Showing the first eight; more decompositions exist.
