Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640696, here are decompositions:

5 + 8640691 = 8640696
7 + 8640689 = 8640696
13 + 8640683 = 8640696
17 + 8640679 = 8640696
109 + 8640587 = 8640696
137 + 8640559 = 8640696
149 + 8640547 = 8640696
193 + 8640503 = 8640696

Showing the first eight; more decompositions exist.
