Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8755480, here are decompositions:

11 + 8755469 = 8755480
29 + 8755451 = 8755480
101 + 8755379 = 8755480
131 + 8755349 = 8755480
137 + 8755343 = 8755480
197 + 8755283 = 8755480
233 + 8755247 = 8755480
263 + 8755217 = 8755480

Showing the first eight; more decompositions exist.
