Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642450, here are decompositions:

67 + 8642383 = 8642450
277 + 8642173 = 8642450
331 + 8642119 = 8642450
373 + 8642077 = 8642450
463 + 8641987 = 8642450
541 + 8641909 = 8642450
577 + 8641873 = 8642450
631 + 8641819 = 8642450

Showing the first eight; more decompositions exist.
