Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668408, here are decompositions:

5 + 8668403 = 8668408
29 + 8668379 = 8668408
41 + 8668367 = 8668408
59 + 8668349 = 8668408
107 + 8668301 = 8668408
251 + 8668157 = 8668408
257 + 8668151 = 8668408
347 + 8668061 = 8668408

Showing the first eight; more decompositions exist.
