Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490910, here are decompositions:

19 + 490891 = 490910
61 + 490849 = 490910
73 + 490837 = 490910
127 + 490783 = 490910
139 + 490771 = 490910
283 + 490627 = 490910
331 + 490579 = 490910
337 + 490573 = 490910

Showing the first eight; more decompositions exist.
