Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670878, here are decompositions:

67 + 8670811 = 8670878
127 + 8670751 = 8670878
199 + 8670679 = 8670878
211 + 8670667 = 8670878
241 + 8670637 = 8670878
379 + 8670499 = 8670878
397 + 8670481 = 8670878
547 + 8670331 = 8670878

Showing the first eight; more decompositions exist.
