Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8755390, here are decompositions:

11 + 8755379 = 8755390
41 + 8755349 = 8755390
47 + 8755343 = 8755390
53 + 8755337 = 8755390
71 + 8755319 = 8755390
107 + 8755283 = 8755390
113 + 8755277 = 8755390
173 + 8755217 = 8755390

Showing the first eight; more decompositions exist.
