Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8755320, here are decompositions:

23 + 8755297 = 8755320
29 + 8755291 = 8755320
37 + 8755283 = 8755320
43 + 8755277 = 8755320
53 + 8755267 = 8755320
73 + 8755247 = 8755320
89 + 8755231 = 8755320
103 + 8755217 = 8755320

Showing the first eight; more decompositions exist.
