Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947540, here are decompositions:

31 + 947509 = 947540
109 + 947431 = 947540
127 + 947413 = 947540
151 + 947389 = 947540
157 + 947383 = 947540
163 + 947377 = 947540
199 + 947341 = 947540
241 + 947299 = 947540

Showing the first eight; more decompositions exist.
