Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642474, here are decompositions:

7 + 8642467 = 8642474
193 + 8642281 = 8642474
277 + 8642197 = 8642474
367 + 8642107 = 8642474
397 + 8642077 = 8642474
487 + 8641987 = 8642474
601 + 8641873 = 8642474
691 + 8641783 = 8642474

Showing the first eight; more decompositions exist.
