Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641048, here are decompositions:

41 + 8641007 = 8641048
71 + 8640977 = 8641048
137 + 8640911 = 8641048
281 + 8640767 = 8641048
347 + 8640701 = 8641048
359 + 8640689 = 8641048
461 + 8640587 = 8641048
641 + 8640407 = 8641048

Showing the first eight; more decompositions exist.
