Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648668, here are decompositions:

131 + 8648537 = 8648668
137 + 8648531 = 8648668
167 + 8648501 = 8648668
401 + 8648267 = 8648668
557 + 8648111 = 8648668
569 + 8648099 = 8648668
701 + 8647967 = 8648668
719 + 8647949 = 8648668

Showing the first eight; more decompositions exist.
