Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640862, here are decompositions:

3 + 8640859 = 8640862
101 + 8640761 = 8640862
149 + 8640713 = 8640862
173 + 8640689 = 8640862
179 + 8640683 = 8640862
359 + 8640503 = 8640862
443 + 8640419 = 8640862
599 + 8640263 = 8640862

Showing the first eight; more decompositions exist.
