Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 974990, here are decompositions:

7 + 974983 = 974990
13 + 974977 = 974990
19 + 974971 = 974990
31 + 974959 = 974990
67 + 974923 = 974990
103 + 974887 = 974990
127 + 974863 = 974990
229 + 974761 = 974990

Showing the first eight; more decompositions exist.
