Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947490, here are decompositions:

7 + 947483 = 947490
41 + 947449 = 947490
59 + 947431 = 947490
67 + 947423 = 947490
73 + 947417 = 947490
79 + 947411 = 947490
83 + 947407 = 947490
101 + 947389 = 947490

Showing the first eight; more decompositions exist.
