Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718878, here are decompositions:

19 + 8718859 = 8718878
67 + 8718811 = 8718878
79 + 8718799 = 8718878
151 + 8718727 = 8718878
229 + 8718649 = 8718878
277 + 8718601 = 8718878
307 + 8718571 = 8718878
409 + 8718469 = 8718878

Showing the first eight; more decompositions exist.
