Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947818, here are decompositions:

71 + 947747 = 947818
89 + 947729 = 947818
107 + 947711 = 947818
167 + 947651 = 947818
191 + 947627 = 947818
197 + 947621 = 947818
239 + 947579 = 947818
257 + 947561 = 947818

Showing the first eight; more decompositions exist.
