Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8741440, here are decompositions:

3 + 8741437 = 8741440
47 + 8741393 = 8741440
131 + 8741309 = 8741440
137 + 8741303 = 8741440
293 + 8741147 = 8741440
311 + 8741129 = 8741440
317 + 8741123 = 8741440
569 + 8740871 = 8741440

Showing the first eight; more decompositions exist.
