Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655556, here are decompositions:

29 + 8655527 = 8655556
59 + 8655497 = 8655556
269 + 8655287 = 8655556
293 + 8655263 = 8655556
359 + 8655197 = 8655556
383 + 8655173 = 8655556
389 + 8655167 = 8655556
509 + 8655047 = 8655556

Showing the first eight; more decompositions exist.
