Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643044, here are decompositions:

31 + 8643013 = 8643044
97 + 8642947 = 8643044
181 + 8642863 = 8643044
271 + 8642773 = 8643044
283 + 8642761 = 8643044
463 + 8642581 = 8643044
577 + 8642467 = 8643044
661 + 8642383 = 8643044

Showing the first eight; more decompositions exist.
