Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643726, here are decompositions:

5 + 8643721 = 8643726
19 + 8643707 = 8643726
29 + 8643697 = 8643726
53 + 8643673 = 8643726
79 + 8643647 = 8643726
107 + 8643619 = 8643726
137 + 8643589 = 8643726
139 + 8643587 = 8643726

Showing the first eight; more decompositions exist.
