Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947218, here are decompositions:

47 + 947171 = 947218
89 + 947129 = 947218
191 + 947027 = 947218
257 + 946961 = 947218
269 + 946949 = 947218
317 + 946901 = 947218
359 + 946859 = 947218
449 + 946769 = 947218

Showing the first eight; more decompositions exist.
