Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947486, here are decompositions:

3 + 947483 = 947486
37 + 947449 = 947486
73 + 947413 = 947486
79 + 947407 = 947486
97 + 947389 = 947486
103 + 947383 = 947486
109 + 947377 = 947486
223 + 947263 = 947486

Showing the first eight; more decompositions exist.
