Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727180, here are decompositions:

17 + 8727163 = 8727180
19 + 8727161 = 8727180
23 + 8727157 = 8727180
31 + 8727149 = 8727180
61 + 8727119 = 8727180
67 + 8727113 = 8727180
71 + 8727109 = 8727180
89 + 8727091 = 8727180

Showing the first eight; more decompositions exist.
