Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727878, here are decompositions:

7 + 8727871 = 8727878
151 + 8727727 = 8727878
277 + 8727601 = 8727878
349 + 8727529 = 8727878
631 + 8727247 = 8727878
769 + 8727109 = 8727878
787 + 8727091 = 8727878
811 + 8727067 = 8727878

Showing the first eight; more decompositions exist.
