Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947858, here are decompositions:

7 + 947851 = 947858
139 + 947719 = 947858
151 + 947707 = 947858
199 + 947659 = 947858
211 + 947647 = 947858
349 + 947509 = 947858
409 + 947449 = 947858
619 + 947239 = 947858

Showing the first eight; more decompositions exist.
