Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669878, here are decompositions:

17 + 8669861 = 8669878
47 + 8669831 = 8669878
101 + 8669777 = 8669878
227 + 8669651 = 8669878
251 + 8669627 = 8669878
257 + 8669621 = 8669878
389 + 8669489 = 8669878
401 + 8669477 = 8669878

Showing the first eight; more decompositions exist.
