Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8755140, here are decompositions:

19 + 8755121 = 8755140
61 + 8755079 = 8755140
67 + 8755073 = 8755140
109 + 8755031 = 8755140
113 + 8755027 = 8755140
139 + 8755001 = 8755140
181 + 8754959 = 8755140
223 + 8754917 = 8755140

Showing the first eight; more decompositions exist.
