Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642534, here are decompositions:

67 + 8642467 = 8642534
151 + 8642383 = 8642534
337 + 8642197 = 8642534
457 + 8642077 = 8642534
547 + 8641987 = 8642534
577 + 8641957 = 8642534
643 + 8641891 = 8642534
661 + 8641873 = 8642534

Showing the first eight; more decompositions exist.
