Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649938, here are decompositions:

67 + 8649871 = 8649938
181 + 8649757 = 8649938
277 + 8649661 = 8649938
421 + 8649517 = 8649938
487 + 8649451 = 8649938
547 + 8649391 = 8649938
571 + 8649367 = 8649938
607 + 8649331 = 8649938

Showing the first eight; more decompositions exist.
