Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490986, here are decompositions:

17 + 490969 = 490986
19 + 490967 = 490986
29 + 490957 = 490986
37 + 490949 = 490986
59 + 490927 = 490986
73 + 490913 = 490986
109 + 490877 = 490986
127 + 490859 = 490986

Showing the first eight; more decompositions exist.
