Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616556, here are decompositions:

23 + 8616533 = 8616556
29 + 8616527 = 8616556
149 + 8616407 = 8616556
233 + 8616323 = 8616556
257 + 8616299 = 8616556
353 + 8616203 = 8616556
359 + 8616197 = 8616556
383 + 8616173 = 8616556

Showing the first eight; more decompositions exist.
