Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947884, here are decompositions:

11 + 947873 = 947884
23 + 947861 = 947884
101 + 947783 = 947884
131 + 947753 = 947884
137 + 947747 = 947884
173 + 947711 = 947884
233 + 947651 = 947884
257 + 947627 = 947884

Showing the first eight; more decompositions exist.
