Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947426, here are decompositions:

3 + 947423 = 947426
13 + 947413 = 947426
19 + 947407 = 947426
37 + 947389 = 947426
43 + 947383 = 947426
127 + 947299 = 947426
163 + 947263 = 947426
223 + 947203 = 947426

Showing the first eight; more decompositions exist.
