Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 976638, here are decompositions:

17 + 976621 = 976638
31 + 976607 = 976638
37 + 976601 = 976638
67 + 976571 = 976638
79 + 976559 = 976638
101 + 976537 = 976638
137 + 976501 = 976638
149 + 976489 = 976638

Showing the first eight; more decompositions exist.
