Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490520, here are decompositions:

61 + 490459 = 490520
67 + 490453 = 490520
103 + 490417 = 490520
127 + 490393 = 490520
181 + 490339 = 490520
211 + 490309 = 490520
271 + 490249 = 490520
313 + 490207 = 490520

Showing the first eight; more decompositions exist.
