Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649676, here are decompositions:

5 + 8649671 = 8649676
47 + 8649629 = 8649676
53 + 8649623 = 8649676
197 + 8649479 = 8649676
257 + 8649419 = 8649676
293 + 8649383 = 8649676
353 + 8649323 = 8649676
359 + 8649317 = 8649676

Showing the first eight; more decompositions exist.
