Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647042, here are decompositions:

11 + 8647031 = 8647042
71 + 8646971 = 8647042
113 + 8646929 = 8647042
191 + 8646851 = 8647042
263 + 8646779 = 8647042
359 + 8646683 = 8647042
461 + 8646581 = 8647042
563 + 8646479 = 8647042

Showing the first eight; more decompositions exist.
