Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947448, here are decompositions:

17 + 947431 = 947448
31 + 947417 = 947448
37 + 947411 = 947448
41 + 947407 = 947448
59 + 947389 = 947448
67 + 947381 = 947448
71 + 947377 = 947448
79 + 947369 = 947448

Showing the first eight; more decompositions exist.
