Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643926, here are decompositions:

3 + 8643923 = 8643926
7 + 8643919 = 8643926
37 + 8643889 = 8643926
139 + 8643787 = 8643926
229 + 8643697 = 8643926
307 + 8643619 = 8643926
337 + 8643589 = 8643926
349 + 8643577 = 8643926

Showing the first eight; more decompositions exist.
