Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490686, here are decompositions:

23 + 490663 = 490686
43 + 490643 = 490686
59 + 490627 = 490686
67 + 490619 = 490686
107 + 490579 = 490686
109 + 490577 = 490686
113 + 490573 = 490686
127 + 490559 = 490686

Showing the first eight; more decompositions exist.
