Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8761440, here are decompositions:

7 + 8761433 = 8761440
11 + 8761429 = 8761440
101 + 8761339 = 8761440
113 + 8761327 = 8761440
137 + 8761303 = 8761440
151 + 8761289 = 8761440
197 + 8761243 = 8761440
227 + 8761213 = 8761440

Showing the first eight; more decompositions exist.
