Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679878, here are decompositions:

7 + 8679871 = 8679878
37 + 8679841 = 8679878
139 + 8679739 = 8679878
271 + 8679607 = 8679878
349 + 8679529 = 8679878
379 + 8679499 = 8679878
421 + 8679457 = 8679878
499 + 8679379 = 8679878

Showing the first eight; more decompositions exist.
