Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637556, here are decompositions:

29 + 8637527 = 8637556
47 + 8637509 = 8637556
89 + 8637467 = 8637556
107 + 8637449 = 8637556
233 + 8637323 = 8637556
293 + 8637263 = 8637556
353 + 8637203 = 8637556
449 + 8637107 = 8637556

Showing the first eight; more decompositions exist.
