Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621880, here are decompositions:

11 + 8621869 = 8621880
13 + 8621867 = 8621880
17 + 8621863 = 8621880
19 + 8621861 = 8621880
23 + 8621857 = 8621880
37 + 8621843 = 8621880
53 + 8621827 = 8621880
61 + 8621819 = 8621880

Showing the first eight; more decompositions exist.
