Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8755980, here are decompositions:

7 + 8755973 = 8755980
17 + 8755963 = 8755980
29 + 8755951 = 8755980
43 + 8755937 = 8755980
59 + 8755921 = 8755980
67 + 8755913 = 8755980
89 + 8755891 = 8755980
127 + 8755853 = 8755980

Showing the first eight; more decompositions exist.
