Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720336, here are decompositions:

19 + 8720317 = 8720336
103 + 8720233 = 8720336
109 + 8720227 = 8720336
199 + 8720137 = 8720336
223 + 8720113 = 8720336
337 + 8719999 = 8720336
349 + 8719987 = 8720336
397 + 8719939 = 8720336

Showing the first eight; more decompositions exist.
