Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617888, here are decompositions:

11 + 8617877 = 8617888
17 + 8617871 = 8617888
89 + 8617799 = 8617888
101 + 8617787 = 8617888
449 + 8617439 = 8617888
491 + 8617397 = 8617888
569 + 8617319 = 8617888
677 + 8617211 = 8617888

Showing the first eight; more decompositions exist.
