Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947666, here are decompositions:

7 + 947659 = 947666
19 + 947647 = 947666
127 + 947539 = 947666
157 + 947509 = 947666
277 + 947389 = 947666
283 + 947383 = 947666
367 + 947299 = 947666
463 + 947203 = 947666

Showing the first eight; more decompositions exist.
