Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8755278, here are decompositions:

11 + 8755267 = 8755278
31 + 8755247 = 8755278
47 + 8755231 = 8755278
61 + 8755217 = 8755278
89 + 8755189 = 8755278
101 + 8755177 = 8755278
137 + 8755141 = 8755278
157 + 8755121 = 8755278

Showing the first eight; more decompositions exist.
