Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642882, here are decompositions:

19 + 8642863 = 8642882
43 + 8642839 = 8642882
109 + 8642773 = 8642882
349 + 8642533 = 8642882
373 + 8642509 = 8642882
433 + 8642449 = 8642882
499 + 8642383 = 8642882
601 + 8642281 = 8642882

Showing the first eight; more decompositions exist.
