Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680140, here are decompositions:

19 + 8680121 = 8680140
37 + 8680103 = 8680140
41 + 8680099 = 8680140
67 + 8680073 = 8680140
97 + 8680043 = 8680140
103 + 8680037 = 8680140
107 + 8680033 = 8680140
113 + 8680027 = 8680140

Showing the first eight; more decompositions exist.
