Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679928, here are decompositions:

29 + 8679899 = 8679928
41 + 8679887 = 8679928
137 + 8679791 = 8679928
251 + 8679677 = 8679928
311 + 8679617 = 8679928
347 + 8679581 = 8679928
401 + 8679527 = 8679928
479 + 8679449 = 8679928

Showing the first eight; more decompositions exist.
