Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680256, here are decompositions:

7 + 8680249 = 8680256
37 + 8680219 = 8680256
43 + 8680213 = 8680256
103 + 8680153 = 8680256
157 + 8680099 = 8680256
223 + 8680033 = 8680256
229 + 8680027 = 8680256
283 + 8679973 = 8680256

Showing the first eight; more decompositions exist.
