Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642934, here are decompositions:

7 + 8642927 = 8642934
23 + 8642911 = 8642934
31 + 8642903 = 8642934
37 + 8642897 = 8642934
71 + 8642863 = 8642934
73 + 8642861 = 8642934
173 + 8642761 = 8642934
211 + 8642723 = 8642934

Showing the first eight; more decompositions exist.
