Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669842, here are decompositions:

11 + 8669831 = 8669842
173 + 8669669 = 8669842
191 + 8669651 = 8669842
353 + 8669489 = 8669842
359 + 8669483 = 8669842
431 + 8669411 = 8669842
443 + 8669399 = 8669842
449 + 8669393 = 8669842

Showing the first eight; more decompositions exist.
