Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680020, here are decompositions:

17 + 8680003 = 8680020
29 + 8679991 = 8680020
47 + 8679973 = 8680020
67 + 8679953 = 8680020
137 + 8679883 = 8680020
149 + 8679871 = 8680020
179 + 8679841 = 8680020
229 + 8679791 = 8680020

Showing the first eight; more decompositions exist.
