Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644396, here are decompositions:

239 + 8644157 = 8644396
347 + 8644049 = 8644396
443 + 8643953 = 8644396
503 + 8643893 = 8644396
557 + 8643839 = 8644396
599 + 8643797 = 8644396
617 + 8643779 = 8644396
647 + 8643749 = 8644396

Showing the first eight; more decompositions exist.
