Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678894, here are decompositions:

31 + 8678863 = 8678894
43 + 8678851 = 8678894
61 + 8678833 = 8678894
73 + 8678821 = 8678894
181 + 8678713 = 8678894
193 + 8678701 = 8678894
223 + 8678671 = 8678894
307 + 8678587 = 8678894

Showing the first eight; more decompositions exist.
