Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668392, here are decompositions:

11 + 8668381 = 8668392
13 + 8668379 = 8668392
23 + 8668369 = 8668392
43 + 8668349 = 8668392
113 + 8668279 = 8668392
191 + 8668201 = 8668392
199 + 8668193 = 8668392
241 + 8668151 = 8668392

Showing the first eight; more decompositions exist.
