Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648556, here are decompositions:

5 + 8648551 = 8648556
13 + 8648543 = 8648556
19 + 8648537 = 8648556
23 + 8648533 = 8648556
43 + 8648513 = 8648556
97 + 8648459 = 8648556
109 + 8648447 = 8648556
167 + 8648389 = 8648556

Showing the first eight; more decompositions exist.
