Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679538, here are decompositions:

11 + 8679527 = 8679538
89 + 8679449 = 8679538
191 + 8679347 = 8679538
227 + 8679311 = 8679538
317 + 8679221 = 8679538
359 + 8679179 = 8679538
401 + 8679137 = 8679538
467 + 8679071 = 8679538

Showing the first eight; more decompositions exist.
