Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637876, here are decompositions:

7 + 8637869 = 8637876
29 + 8637847 = 8637876
47 + 8637829 = 8637876
89 + 8637787 = 8637876
97 + 8637779 = 8637876
127 + 8637749 = 8637876
179 + 8637697 = 8637876
239 + 8637637 = 8637876

Showing the first eight; more decompositions exist.
