Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717240, here are decompositions:

109 + 8717131 = 8717240
127 + 8717113 = 8717240
199 + 8717041 = 8717240
229 + 8717011 = 8717240
241 + 8716999 = 8717240
283 + 8716957 = 8717240
349 + 8716891 = 8717240
379 + 8716861 = 8717240

Showing the first eight; more decompositions exist.
