Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8755920, here are decompositions:

7 + 8755913 = 8755920
29 + 8755891 = 8755920
31 + 8755889 = 8755920
67 + 8755853 = 8755920
71 + 8755849 = 8755920
79 + 8755841 = 8755920
97 + 8755823 = 8755920
101 + 8755819 = 8755920

Showing the first eight; more decompositions exist.
