Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727538, here are decompositions:

41 + 8727497 = 8727538
107 + 8727431 = 8727538
179 + 8727359 = 8727538
251 + 8727287 = 8727538
269 + 8727269 = 8727538
359 + 8727179 = 8727538
389 + 8727149 = 8727538
419 + 8727119 = 8727538

Showing the first eight; more decompositions exist.
