Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680128, here are decompositions:

7 + 8680121 = 8680128
29 + 8680099 = 8680128
101 + 8680027 = 8680128
137 + 8679991 = 8680128
157 + 8679971 = 8680128
229 + 8679899 = 8680128
241 + 8679887 = 8680128
257 + 8679871 = 8680128

Showing the first eight; more decompositions exist.
