Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490958, here are decompositions:

7 + 490951 = 490958
31 + 490927 = 490958
37 + 490921 = 490958
67 + 490891 = 490958
109 + 490849 = 490958
331 + 490627 = 490958
367 + 490591 = 490958
379 + 490579 = 490958

Showing the first eight; more decompositions exist.
