Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621936, here are decompositions:

3 + 8621933 = 8621936
67 + 8621869 = 8621936
73 + 8621863 = 8621936
79 + 8621857 = 8621936
109 + 8621827 = 8621936
139 + 8621797 = 8621936
157 + 8621779 = 8621936
163 + 8621773 = 8621936

Showing the first eight; more decompositions exist.
