Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640874, here are decompositions:

3 + 8640871 = 8640874
107 + 8640767 = 8640874
113 + 8640761 = 8640874
167 + 8640707 = 8640874
173 + 8640701 = 8640874
191 + 8640683 = 8640874
467 + 8640407 = 8640874
587 + 8640287 = 8640874

Showing the first eight; more decompositions exist.
