Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648644, here are decompositions:

101 + 8648543 = 8648644
107 + 8648537 = 8648644
113 + 8648531 = 8648644
131 + 8648513 = 8648644
197 + 8648447 = 8648644
311 + 8648333 = 8648644
647 + 8647997 = 8648644
677 + 8647967 = 8648644

Showing the first eight; more decompositions exist.
