Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646874, here are decompositions:

23 + 8646851 = 8646874
53 + 8646821 = 8646874
167 + 8646707 = 8646874
191 + 8646683 = 8646874
293 + 8646581 = 8646874
557 + 8646317 = 8646874
617 + 8646257 = 8646874
641 + 8646233 = 8646874

Showing the first eight; more decompositions exist.
