Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947928, here are decompositions:

11 + 947917 = 947928
17 + 947911 = 947928
67 + 947861 = 947928
71 + 947857 = 947928
109 + 947819 = 947928
181 + 947747 = 947928
199 + 947729 = 947928
269 + 947659 = 947928

Showing the first eight; more decompositions exist.
