Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643122, here are decompositions:

13 + 8643109 = 8643122
31 + 8643091 = 8643122
109 + 8643013 = 8643122
211 + 8642911 = 8643122
283 + 8642839 = 8643122
349 + 8642773 = 8643122
541 + 8642581 = 8643122
613 + 8642509 = 8643122

Showing the first eight; more decompositions exist.
