Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8755380, here are decompositions:

31 + 8755349 = 8755380
37 + 8755343 = 8755380
41 + 8755339 = 8755380
43 + 8755337 = 8755380
59 + 8755321 = 8755380
61 + 8755319 = 8755380
83 + 8755297 = 8755380
89 + 8755291 = 8755380

Showing the first eight; more decompositions exist.
