Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680180, here are decompositions:

23 + 8680157 = 8680180
59 + 8680121 = 8680180
107 + 8680073 = 8680180
137 + 8680043 = 8680180
227 + 8679953 = 8680180
281 + 8679899 = 8680180
293 + 8679887 = 8680180
389 + 8679791 = 8680180

Showing the first eight; more decompositions exist.
