Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740440, here are decompositions:

11 + 8740429 = 8740440
13 + 8740427 = 8740440
29 + 8740411 = 8740440
47 + 8740393 = 8740440
53 + 8740387 = 8740440
67 + 8740373 = 8740440
73 + 8740367 = 8740440
103 + 8740337 = 8740440

Showing the first eight; more decompositions exist.
