Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 968640, here are decompositions:

47 + 968593 = 968640
67 + 968573 = 968640
73 + 968567 = 968640
83 + 968557 = 968640
103 + 968537 = 968640
137 + 968503 = 968640
139 + 968501 = 968640
173 + 968467 = 968640

Showing the first eight; more decompositions exist.
