Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643056, here are decompositions:

3 + 8643053 = 8643056
43 + 8643013 = 8643056
67 + 8642989 = 8643056
109 + 8642947 = 8643056
193 + 8642863 = 8643056
199 + 8642857 = 8643056
283 + 8642773 = 8643056
523 + 8642533 = 8643056

Showing the first eight; more decompositions exist.
