Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615556, here are decompositions:

13 + 8615543 = 8615556
17 + 8615539 = 8615556
29 + 8615527 = 8615556
43 + 8615513 = 8615556
83 + 8615473 = 8615556
167 + 8615389 = 8615556
179 + 8615377 = 8615556
223 + 8615333 = 8615556

Showing the first eight; more decompositions exist.
