Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679940, here are decompositions:

41 + 8679899 = 8679940
53 + 8679887 = 8679940
149 + 8679791 = 8679940
173 + 8679767 = 8679940
197 + 8679743 = 8679940
263 + 8679677 = 8679940
359 + 8679581 = 8679940
383 + 8679557 = 8679940

Showing the first eight; more decompositions exist.
