Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490912, here are decompositions:

53 + 490859 = 490912
83 + 490829 = 490912
179 + 490733 = 490912
251 + 490661 = 490912
269 + 490643 = 490912
281 + 490631 = 490912
293 + 490619 = 490912
353 + 490559 = 490912

Showing the first eight; more decompositions exist.
