Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668398, here are decompositions:

17 + 8668381 = 8668398
19 + 8668379 = 8668398
29 + 8668369 = 8668398
31 + 8668367 = 8668398
41 + 8668357 = 8668398
97 + 8668301 = 8668398
131 + 8668267 = 8668398
191 + 8668207 = 8668398

Showing the first eight; more decompositions exist.
