Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621888, here are decompositions:

19 + 8621869 = 8621888
31 + 8621857 = 8621888
61 + 8621827 = 8621888
109 + 8621779 = 8621888
139 + 8621749 = 8621888
181 + 8621707 = 8621888
211 + 8621677 = 8621888
271 + 8621617 = 8621888

Showing the first eight; more decompositions exist.
