Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489794, here are decompositions:

3 + 489791 = 489794
61 + 489733 = 489794
103 + 489691 = 489794
163 + 489631 = 489794
181 + 489613 = 489794
223 + 489571 = 489794
241 + 489553 = 489794
307 + 489487 = 489794

Showing the first eight; more decompositions exist.
