Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489890, here are decompositions:

3 + 489887 = 489890
19 + 489871 = 489890
43 + 489847 = 489890
67 + 489823 = 489890
73 + 489817 = 489890
97 + 489793 = 489890
157 + 489733 = 489890
199 + 489691 = 489890

Showing the first eight; more decompositions exist.
