Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679388, here are decompositions:

41 + 8679347 = 8679388
167 + 8679221 = 8679388
251 + 8679137 = 8679388
317 + 8679071 = 8679388
449 + 8678939 = 8679388
461 + 8678927 = 8679388
647 + 8678741 = 8679388
719 + 8678669 = 8679388

Showing the first eight; more decompositions exist.
