Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490988, here are decompositions:

19 + 490969 = 490988
31 + 490957 = 490988
37 + 490951 = 490988
61 + 490927 = 490988
67 + 490921 = 490988
97 + 490891 = 490988
139 + 490849 = 490988
151 + 490837 = 490988

Showing the first eight; more decompositions exist.
