Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641726, here are decompositions:

17 + 8641709 = 8641726
29 + 8641697 = 8641726
53 + 8641673 = 8641726
83 + 8641643 = 8641726
113 + 8641613 = 8641726
179 + 8641547 = 8641726
257 + 8641469 = 8641726
293 + 8641433 = 8641726

Showing the first eight; more decompositions exist.
