Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727238, here are decompositions:

41 + 8727197 = 8727238
59 + 8727179 = 8727238
89 + 8727149 = 8727238
251 + 8726987 = 8727238
269 + 8726969 = 8727238
281 + 8726957 = 8727238
389 + 8726849 = 8727238
449 + 8726789 = 8727238

Showing the first eight; more decompositions exist.
