Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728494, here are decompositions:

11 + 8728483 = 8728494
13 + 8728481 = 8728494
23 + 8728471 = 8728494
37 + 8728457 = 8728494
67 + 8728427 = 8728494
97 + 8728397 = 8728494
107 + 8728387 = 8728494
113 + 8728381 = 8728494

Showing the first eight; more decompositions exist.
