Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8654398, here are decompositions:

17 + 8654381 = 8654398
41 + 8654357 = 8654398
47 + 8654351 = 8654398
59 + 8654339 = 8654398
149 + 8654249 = 8654398
167 + 8654231 = 8654398
197 + 8654201 = 8654398
227 + 8654171 = 8654398

Showing the first eight; more decompositions exist.
