Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657556, here are decompositions:

23 + 8657533 = 8657556
43 + 8657513 = 8657556
53 + 8657503 = 8657556
107 + 8657449 = 8657556
179 + 8657377 = 8657556
199 + 8657357 = 8657556
223 + 8657333 = 8657556
233 + 8657323 = 8657556

Showing the first eight; more decompositions exist.
