Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617556, here are decompositions:

7 + 8617549 = 8617556
37 + 8617519 = 8617556
43 + 8617513 = 8617556
109 + 8617447 = 8617556
139 + 8617417 = 8617556
223 + 8617333 = 8617556
229 + 8617327 = 8617556
349 + 8617207 = 8617556

Showing the first eight; more decompositions exist.
