Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727672, here are decompositions:

13 + 8727659 = 8727672
29 + 8727643 = 8727672
53 + 8727619 = 8727672
61 + 8727611 = 8727672
71 + 8727601 = 8727672
73 + 8727599 = 8727672
89 + 8727583 = 8727672
103 + 8727569 = 8727672

Showing the first eight; more decompositions exist.
