Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643756, here are decompositions:

7 + 8643749 = 8643756
59 + 8643697 = 8643756
83 + 8643673 = 8643756
109 + 8643647 = 8643756
137 + 8643619 = 8643756
167 + 8643589 = 8643756
179 + 8643577 = 8643756
193 + 8643563 = 8643756

Showing the first eight; more decompositions exist.
