Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947866, here are decompositions:

5 + 947861 = 947866
47 + 947819 = 947866
83 + 947783 = 947866
113 + 947753 = 947866
137 + 947729 = 947866
239 + 947627 = 947866
263 + 947603 = 947866
383 + 947483 = 947866

Showing the first eight; more decompositions exist.
