Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947690, here are decompositions:

31 + 947659 = 947690
43 + 947647 = 947690
151 + 947539 = 947690
181 + 947509 = 947690
241 + 947449 = 947690
277 + 947413 = 947690
283 + 947407 = 947690
307 + 947383 = 947690

Showing the first eight; more decompositions exist.
