Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643424, here are decompositions:

107 + 8643317 = 8643424
137 + 8643287 = 8643424
227 + 8643197 = 8643424
281 + 8643143 = 8643424
347 + 8643077 = 8643424
401 + 8643023 = 8643424
521 + 8642903 = 8643424
563 + 8642861 = 8643424

Showing the first eight; more decompositions exist.
