Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680280, here are decompositions:

3 + 8680277 = 8680280
13 + 8680267 = 8680280
31 + 8680249 = 8680280
61 + 8680219 = 8680280
67 + 8680213 = 8680280
79 + 8680201 = 8680280
109 + 8680171 = 8680280
127 + 8680153 = 8680280

Showing the first eight; more decompositions exist.
