Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8755520, here are decompositions:

3 + 8755517 = 8755520
19 + 8755501 = 8755520
127 + 8755393 = 8755520
139 + 8755381 = 8755520
181 + 8755339 = 8755520
199 + 8755321 = 8755520
223 + 8755297 = 8755520
229 + 8755291 = 8755520

Showing the first eight; more decompositions exist.
