Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679278, here are decompositions:

7 + 8679271 = 8679278
61 + 8679217 = 8679278
79 + 8679199 = 8679278
199 + 8679079 = 8679278
241 + 8679037 = 8679278
331 + 8678947 = 8679278
337 + 8678941 = 8679278
379 + 8678899 = 8679278

Showing the first eight; more decompositions exist.
