Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490998, here are decompositions:

5 + 490993 = 490998
7 + 490991 = 490998
29 + 490969 = 490998
31 + 490967 = 490998
41 + 490957 = 490998
47 + 490951 = 490998
61 + 490937 = 490998
71 + 490927 = 490998

Showing the first eight; more decompositions exist.
