Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489770, here are decompositions:

37 + 489733 = 489770
79 + 489691 = 489770
97 + 489673 = 489770
139 + 489631 = 489770
157 + 489613 = 489770
199 + 489571 = 489770
241 + 489529 = 489770
277 + 489493 = 489770

Showing the first eight; more decompositions exist.
