Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947918, here are decompositions:

7 + 947911 = 947918
61 + 947857 = 947918
67 + 947851 = 947918
199 + 947719 = 947918
211 + 947707 = 947918
271 + 947647 = 947918
277 + 947641 = 947918
379 + 947539 = 947918

Showing the first eight; more decompositions exist.
