Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8755120, here are decompositions:

41 + 8755079 = 8755120
47 + 8755073 = 8755120
71 + 8755049 = 8755120
89 + 8755031 = 8755120
149 + 8754971 = 8755120
251 + 8754869 = 8755120
347 + 8754773 = 8755120
389 + 8754731 = 8755120

Showing the first eight; more decompositions exist.
