Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947178, here are decompositions:

7 + 947171 = 947178
41 + 947137 = 947178
59 + 947119 = 947178
151 + 947027 = 947178
181 + 946997 = 947178
191 + 946987 = 947178
229 + 946949 = 947178
277 + 946901 = 947178

Showing the first eight; more decompositions exist.
