Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8755478, here are decompositions:

79 + 8755399 = 8755478
97 + 8755381 = 8755478
139 + 8755339 = 8755478
157 + 8755321 = 8755478
181 + 8755297 = 8755478
211 + 8755267 = 8755478
337 + 8755141 = 8755478
499 + 8754979 = 8755478

Showing the first eight; more decompositions exist.
