Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489806, here are decompositions:

3 + 489803 = 489806
7 + 489799 = 489806
13 + 489793 = 489806
73 + 489733 = 489806
127 + 489679 = 489806
193 + 489613 = 489806
277 + 489529 = 489806
313 + 489493 = 489806

Showing the first eight; more decompositions exist.
