Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668420, here are decompositions:

17 + 8668403 = 8668420
41 + 8668379 = 8668420
53 + 8668367 = 8668420
71 + 8668349 = 8668420
227 + 8668193 = 8668420
263 + 8668157 = 8668420
269 + 8668151 = 8668420
347 + 8668073 = 8668420

Showing the first eight; more decompositions exist.
