Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668126, here are decompositions:

53 + 8668073 = 8668126
59 + 8668067 = 8668126
83 + 8668043 = 8668126
197 + 8667929 = 8668126
227 + 8667899 = 8668126
263 + 8667863 = 8668126
317 + 8667809 = 8668126
419 + 8667707 = 8668126

Showing the first eight; more decompositions exist.
