Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643074, here are decompositions:

61 + 8643013 = 8643074
127 + 8642947 = 8643074
163 + 8642911 = 8643074
211 + 8642863 = 8643074
313 + 8642761 = 8643074
541 + 8642533 = 8643074
607 + 8642467 = 8643074
691 + 8642383 = 8643074

Showing the first eight; more decompositions exist.
