Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490442, here are decompositions:

103 + 490339 = 490442
193 + 490249 = 490442
241 + 490201 = 490442
283 + 490159 = 490442
331 + 490111 = 490442
409 + 490033 = 490442
439 + 490003 = 490442
499 + 489943 = 490442

Showing the first eight; more decompositions exist.
