Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490238, here are decompositions:

31 + 490207 = 490238
37 + 490201 = 490238
79 + 490159 = 490238
127 + 490111 = 490238
181 + 490057 = 490238
277 + 489961 = 490238
337 + 489901 = 490238
367 + 489871 = 490238

Showing the first eight; more decompositions exist.
