Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490938, here are decompositions:

11 + 490927 = 490938
17 + 490921 = 490938
47 + 490891 = 490938
61 + 490877 = 490938
79 + 490859 = 490938
89 + 490849 = 490938
101 + 490837 = 490938
109 + 490829 = 490938

Showing the first eight; more decompositions exist.
