Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8755440, here are decompositions:

41 + 8755399 = 8755440
47 + 8755393 = 8755440
59 + 8755381 = 8755440
61 + 8755379 = 8755440
97 + 8755343 = 8755440
101 + 8755339 = 8755440
103 + 8755337 = 8755440
149 + 8755291 = 8755440

Showing the first eight; more decompositions exist.
