Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679748, here are decompositions:

5 + 8679743 = 8679748
71 + 8679677 = 8679748
107 + 8679641 = 8679748
131 + 8679617 = 8679748
167 + 8679581 = 8679748
191 + 8679557 = 8679748
197 + 8679551 = 8679748
401 + 8679347 = 8679748

Showing the first eight; more decompositions exist.
