Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490298, here are decompositions:

31 + 490267 = 490298
97 + 490201 = 490298
139 + 490159 = 490298
181 + 490117 = 490298
241 + 490057 = 490298
337 + 489961 = 490298
397 + 489901 = 490298
499 + 489799 = 490298

Showing the first eight; more decompositions exist.
