Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645898, here are decompositions:

11 + 8645887 = 8645898
109 + 8645789 = 8645898
137 + 8645761 = 8645898
139 + 8645759 = 8645898
179 + 8645719 = 8645898
211 + 8645687 = 8645898
229 + 8645669 = 8645898
241 + 8645657 = 8645898

Showing the first eight; more decompositions exist.
