Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679982, here are decompositions:

11 + 8679971 = 8679982
29 + 8679953 = 8679982
83 + 8679899 = 8679982
191 + 8679791 = 8679982
239 + 8679743 = 8679982
401 + 8679581 = 8679982
431 + 8679551 = 8679982
761 + 8679221 = 8679982

Showing the first eight; more decompositions exist.
