Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490008, here are decompositions:

5 + 490003 = 490008
7 + 490001 = 490008
19 + 489989 = 490008
31 + 489977 = 490008
47 + 489961 = 490008
67 + 489941 = 490008
97 + 489911 = 490008
107 + 489901 = 490008

Showing the first eight; more decompositions exist.
