Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640694, here are decompositions:

3 + 8640691 = 8640694
5 + 8640689 = 8640694
11 + 8640683 = 8640694
107 + 8640587 = 8640694
191 + 8640503 = 8640694
431 + 8640263 = 8640694
443 + 8640251 = 8640694
677 + 8640017 = 8640694

Showing the first eight; more decompositions exist.
