Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656446, here are decompositions:

13 + 8656433 = 8656446
23 + 8656423 = 8656446
47 + 8656399 = 8656446
53 + 8656393 = 8656446
67 + 8656379 = 8656446
79 + 8656367 = 8656446
83 + 8656363 = 8656446
89 + 8656357 = 8656446

Showing the first eight; more decompositions exist.
