Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668412, here are decompositions:

31 + 8668381 = 8668412
43 + 8668369 = 8668412
139 + 8668273 = 8668412
211 + 8668201 = 8668412
271 + 8668141 = 8668412
331 + 8668081 = 8668412
349 + 8668063 = 8668412
433 + 8667979 = 8668412

Showing the first eight; more decompositions exist.
