Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641006, here are decompositions:

29 + 8640977 = 8641006
239 + 8640767 = 8641006
293 + 8640713 = 8641006
317 + 8640689 = 8641006
419 + 8640587 = 8641006
503 + 8640503 = 8641006
587 + 8640419 = 8641006
599 + 8640407 = 8641006

Showing the first eight; more decompositions exist.
