Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679340, here are decompositions:

29 + 8679311 = 8679340
269 + 8679071 = 8679340
281 + 8679059 = 8679340
389 + 8678951 = 8679340
401 + 8678939 = 8679340
557 + 8678783 = 8679340
563 + 8678777 = 8679340
587 + 8678753 = 8679340

Showing the first eight; more decompositions exist.
