Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727838, here are decompositions:

29 + 8727809 = 8727838
47 + 8727791 = 8727838
59 + 8727779 = 8727838
71 + 8727767 = 8727838
107 + 8727731 = 8727838
137 + 8727701 = 8727838
149 + 8727689 = 8727838
179 + 8727659 = 8727838

Showing the first eight; more decompositions exist.
