Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642876, here are decompositions:

13 + 8642863 = 8642876
19 + 8642857 = 8642876
37 + 8642839 = 8642876
103 + 8642773 = 8642876
367 + 8642509 = 8642876
409 + 8642467 = 8642876
547 + 8642329 = 8642876
757 + 8642119 = 8642876

Showing the first eight; more decompositions exist.
