Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640706, here are decompositions:

3 + 8640703 = 8640706
5 + 8640701 = 8640706
17 + 8640689 = 8640706
23 + 8640683 = 8640706
419 + 8640287 = 8640706
443 + 8640263 = 8640706
509 + 8640197 = 8640706
647 + 8640059 = 8640706

Showing the first eight; more decompositions exist.
