Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649416, here are decompositions:

7 + 8649409 = 8649416
67 + 8649349 = 8649416
73 + 8649343 = 8649416
163 + 8649253 = 8649416
229 + 8649187 = 8649416
313 + 8649103 = 8649416
337 + 8649079 = 8649416
367 + 8649049 = 8649416

Showing the first eight; more decompositions exist.
