Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8706878, here are decompositions:

7 + 8706871 = 8706878
127 + 8706751 = 8706878
151 + 8706727 = 8706878
211 + 8706667 = 8706878
331 + 8706547 = 8706878
421 + 8706457 = 8706878
541 + 8706337 = 8706878
601 + 8706277 = 8706878

Showing the first eight; more decompositions exist.
