Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621934, here are decompositions:

7 + 8621927 = 8621934
23 + 8621911 = 8621934
37 + 8621897 = 8621934
67 + 8621867 = 8621934
71 + 8621863 = 8621934
73 + 8621861 = 8621934
103 + 8621831 = 8621934
107 + 8621827 = 8621934

Showing the first eight; more decompositions exist.
