Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637936, here are decompositions:

7 + 8637929 = 8637936
67 + 8637869 = 8637936
89 + 8637847 = 8637936
107 + 8637829 = 8637936
149 + 8637787 = 8637936
157 + 8637779 = 8637936
239 + 8637697 = 8637936
269 + 8637667 = 8637936

Showing the first eight; more decompositions exist.
