Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 976640, here are decompositions:

3 + 976637 = 976640
19 + 976621 = 976640
79 + 976561 = 976640
103 + 976537 = 976640
127 + 976513 = 976640
139 + 976501 = 976640
151 + 976489 = 976640
157 + 976483 = 976640

Showing the first eight; more decompositions exist.
