Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728126, here are decompositions:

47 + 8728079 = 8728126
53 + 8728073 = 8728126
89 + 8728037 = 8728126
137 + 8727989 = 8728126
227 + 8727899 = 8728126
269 + 8727857 = 8728126
317 + 8727809 = 8728126
347 + 8727779 = 8728126

Showing the first eight; more decompositions exist.
