Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490146, here are decompositions:

29 + 490117 = 490146
43 + 490103 = 490146
89 + 490057 = 490146
113 + 490033 = 490146
127 + 490019 = 490146
157 + 489989 = 490146
233 + 489913 = 490146
277 + 489869 = 490146

Showing the first eight; more decompositions exist.
