Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728410, here are decompositions:

13 + 8728397 = 8728410
23 + 8728387 = 8728410
29 + 8728381 = 8728410
37 + 8728373 = 8728410
79 + 8728331 = 8728410
101 + 8728309 = 8728410
107 + 8728303 = 8728410
137 + 8728273 = 8728410

Showing the first eight; more decompositions exist.
