Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679980, here are decompositions:

7 + 8679973 = 8679980
37 + 8679943 = 8679980
97 + 8679883 = 8679980
109 + 8679871 = 8679980
139 + 8679841 = 8679980
241 + 8679739 = 8679980
271 + 8679709 = 8679980
373 + 8679607 = 8679980

Showing the first eight; more decompositions exist.
