Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648078, here are decompositions:

151 + 8647927 = 8648078
181 + 8647897 = 8648078
199 + 8647879 = 8648078
277 + 8647801 = 8648078
367 + 8647711 = 8648078
379 + 8647699 = 8648078
421 + 8647657 = 8648078
499 + 8647579 = 8648078

Showing the first eight; more decompositions exist.
