Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728316, here are decompositions:

7 + 8728309 = 8728316
13 + 8728303 = 8728316
43 + 8728273 = 8728316
109 + 8728207 = 8728316
379 + 8727937 = 8728316
409 + 8727907 = 8728316
643 + 8727673 = 8728316
673 + 8727643 = 8728316

Showing the first eight; more decompositions exist.
