Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490184, here are decompositions:

67 + 490117 = 490184
73 + 490111 = 490184
127 + 490057 = 490184
151 + 490033 = 490184
181 + 490003 = 490184
223 + 489961 = 490184
241 + 489943 = 490184
271 + 489913 = 490184

Showing the first eight; more decompositions exist.
