Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679820, here are decompositions:

29 + 8679791 = 8679820
53 + 8679767 = 8679820
179 + 8679641 = 8679820
239 + 8679581 = 8679820
263 + 8679557 = 8679820
269 + 8679551 = 8679820
293 + 8679527 = 8679820
467 + 8679353 = 8679820

Showing the first eight; more decompositions exist.
