Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 949640, here are decompositions:

7 + 949633 = 949640
19 + 949621 = 949640
31 + 949609 = 949640
73 + 949567 = 949640
127 + 949513 = 949640
163 + 949477 = 949640
199 + 949441 = 949640
337 + 949303 = 949640

Showing the first eight; more decompositions exist.
