Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688842, here are decompositions:

13 + 8688829 = 8688842
103 + 8688739 = 8688842
139 + 8688703 = 8688842
229 + 8688613 = 8688842
241 + 8688601 = 8688842
271 + 8688571 = 8688842
373 + 8688469 = 8688842
433 + 8688409 = 8688842

Showing the first eight; more decompositions exist.
