Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679780, here are decompositions:

13 + 8679767 = 8679780
37 + 8679743 = 8679780
41 + 8679739 = 8679780
71 + 8679709 = 8679780
103 + 8679677 = 8679780
139 + 8679641 = 8679780
163 + 8679617 = 8679780
173 + 8679607 = 8679780

Showing the first eight; more decompositions exist.
