Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636556, here are decompositions:

7 + 8636549 = 8636556
13 + 8636543 = 8636556
17 + 8636539 = 8636556
23 + 8636533 = 8636556
43 + 8636513 = 8636556
83 + 8636473 = 8636556
107 + 8636449 = 8636556
167 + 8636389 = 8636556

Showing the first eight; more decompositions exist.
