Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727080, here are decompositions:

13 + 8727067 = 8727080
31 + 8727049 = 8727080
97 + 8726983 = 8727080
127 + 8726953 = 8727080
157 + 8726923 = 8727080
163 + 8726917 = 8727080
277 + 8726803 = 8727080
367 + 8726713 = 8727080

Showing the first eight; more decompositions exist.
