Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8760440, here are decompositions:

19 + 8760421 = 8760440
37 + 8760403 = 8760440
67 + 8760373 = 8760440
103 + 8760337 = 8760440
109 + 8760331 = 8760440
151 + 8760289 = 8760440
193 + 8760247 = 8760440
211 + 8760229 = 8760440

Showing the first eight; more decompositions exist.
