Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490006, here are decompositions:

3 + 490003 = 490006
5 + 490001 = 490006
17 + 489989 = 490006
29 + 489977 = 490006
47 + 489959 = 490006
137 + 489869 = 490006
173 + 489833 = 490006
263 + 489743 = 490006

Showing the first eight; more decompositions exist.
