Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947664, here are decompositions:

5 + 947659 = 947664
13 + 947651 = 947664
17 + 947647 = 947664
23 + 947641 = 947664
37 + 947627 = 947664
43 + 947621 = 947664
61 + 947603 = 947664
103 + 947561 = 947664

Showing the first eight; more decompositions exist.
