Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8665398, here are decompositions:

29 + 8665369 = 8665398
37 + 8665361 = 8665398
41 + 8665357 = 8665398
139 + 8665259 = 8665398
179 + 8665219 = 8665398
191 + 8665207 = 8665398
197 + 8665201 = 8665398
241 + 8665157 = 8665398

Showing the first eight; more decompositions exist.
