Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679400, here are decompositions:

3 + 8679397 = 8679400
47 + 8679353 = 8679400
53 + 8679347 = 8679400
89 + 8679311 = 8679400
179 + 8679221 = 8679400
263 + 8679137 = 8679400
449 + 8678951 = 8679400
461 + 8678939 = 8679400

Showing the first eight; more decompositions exist.
