Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947938, here are decompositions:

11 + 947927 = 947938
191 + 947747 = 947938
197 + 947741 = 947938
227 + 947711 = 947938
311 + 947627 = 947938
317 + 947621 = 947938
359 + 947579 = 947938
521 + 947417 = 947938

Showing the first eight; more decompositions exist.
