Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621874, here are decompositions:

5 + 8621869 = 8621874
7 + 8621867 = 8621874
11 + 8621863 = 8621874
13 + 8621861 = 8621874
17 + 8621857 = 8621874
31 + 8621843 = 8621874
43 + 8621831 = 8621874
47 + 8621827 = 8621874

Showing the first eight; more decompositions exist.
