Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490086, here are decompositions:

29 + 490057 = 490086
53 + 490033 = 490086
67 + 490019 = 490086
83 + 490003 = 490086
97 + 489989 = 490086
109 + 489977 = 490086
127 + 489959 = 490086
173 + 489913 = 490086

Showing the first eight; more decompositions exist.
