Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668746, here are decompositions:

5 + 8668741 = 8668746
7 + 8668739 = 8668746
59 + 8668687 = 8668746
103 + 8668643 = 8668746
109 + 8668637 = 8668746
137 + 8668609 = 8668746
193 + 8668553 = 8668746
197 + 8668549 = 8668746

Showing the first eight; more decompositions exist.
