Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639556, here are decompositions:

5 + 8639551 = 8639556
7 + 8639549 = 8639556
17 + 8639539 = 8639556
97 + 8639459 = 8639556
103 + 8639453 = 8639556
113 + 8639443 = 8639556
193 + 8639363 = 8639556
257 + 8639299 = 8639556

Showing the first eight; more decompositions exist.
