Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715440, here are decompositions:

31 + 8715409 = 8715440
37 + 8715403 = 8715440
79 + 8715361 = 8715440
103 + 8715337 = 8715440
337 + 8715103 = 8715440
421 + 8715019 = 8715440
457 + 8714983 = 8715440
499 + 8714941 = 8715440

Showing the first eight; more decompositions exist.
