Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668452, here are decompositions:

29 + 8668423 = 8668452
31 + 8668421 = 8668452
71 + 8668381 = 8668452
73 + 8668379 = 8668452
83 + 8668369 = 8668452
103 + 8668349 = 8668452
151 + 8668301 = 8668452
173 + 8668279 = 8668452

Showing the first eight; more decompositions exist.
