Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667888, here are decompositions:

17 + 8667871 = 8667888
41 + 8667847 = 8667888
59 + 8667829 = 8667888
67 + 8667821 = 8667888
79 + 8667809 = 8667888
167 + 8667721 = 8667888
181 + 8667707 = 8667888
191 + 8667697 = 8667888

Showing the first eight; more decompositions exist.
