Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643694, here are decompositions:

23 + 8643671 = 8643694
47 + 8643647 = 8643694
107 + 8643587 = 8643694
131 + 8643563 = 8643694
167 + 8643527 = 8643694
173 + 8643521 = 8643694
251 + 8643443 = 8643694
557 + 8643137 = 8643694

Showing the first eight; more decompositions exist.
