Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8755218, here are decompositions:

29 + 8755189 = 8755218
41 + 8755177 = 8755218
97 + 8755121 = 8755218
139 + 8755079 = 8755218
191 + 8755027 = 8755218
239 + 8754979 = 8755218
347 + 8754871 = 8755218
349 + 8754869 = 8755218

Showing the first eight; more decompositions exist.
