Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490974, here are decompositions:

5 + 490969 = 490974
7 + 490967 = 490974
17 + 490957 = 490974
23 + 490951 = 490974
37 + 490937 = 490974
47 + 490927 = 490974
53 + 490921 = 490974
61 + 490913 = 490974

Showing the first eight; more decompositions exist.
