Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643124, here are decompositions:

3 + 8643121 = 8643124
41 + 8643083 = 8643124
47 + 8643077 = 8643124
71 + 8643053 = 8643124
101 + 8643023 = 8643124
173 + 8642951 = 8643124
197 + 8642927 = 8643124
227 + 8642897 = 8643124

Showing the first eight; more decompositions exist.
