Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679842, here are decompositions:

103 + 8679739 = 8679842
313 + 8679529 = 8679842
463 + 8679379 = 8679842
571 + 8679271 = 8679842
643 + 8679199 = 8679842
733 + 8679109 = 8679842
991 + 8678851 = 8679842
1009 + 8678833 = 8679842

Showing the first eight; more decompositions exist.
