Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668450, here are decompositions:

29 + 8668421 = 8668450
47 + 8668403 = 8668450
71 + 8668379 = 8668450
83 + 8668367 = 8668450
101 + 8668349 = 8668450
149 + 8668301 = 8668450
257 + 8668193 = 8668450
293 + 8668157 = 8668450

Showing the first eight; more decompositions exist.
