Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489826, here are decompositions:

3 + 489823 = 489826
23 + 489803 = 489826
83 + 489743 = 489826
137 + 489689 = 489826
149 + 489677 = 489826
167 + 489659 = 489826
173 + 489653 = 489826
269 + 489557 = 489826

Showing the first eight; more decompositions exist.
