Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8755020, here are decompositions:

19 + 8755001 = 8755020
41 + 8754979 = 8755020
61 + 8754959 = 8755020
89 + 8754931 = 8755020
101 + 8754919 = 8755020
103 + 8754917 = 8755020
107 + 8754913 = 8755020
137 + 8754883 = 8755020

Showing the first eight; more decompositions exist.
