Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 942640, here are decompositions:

3 + 942637 = 942640
47 + 942593 = 942640
71 + 942569 = 942640
113 + 942527 = 942640
131 + 942509 = 942640
191 + 942449 = 942640
239 + 942401 = 942640
269 + 942371 = 942640

Showing the first eight; more decompositions exist.
