Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8753440, here are decompositions:

71 + 8753369 = 8753440
149 + 8753291 = 8753440
173 + 8753267 = 8753440
233 + 8753207 = 8753440
251 + 8753189 = 8753440
263 + 8753177 = 8753440
389 + 8753051 = 8753440
419 + 8753021 = 8753440

Showing the first eight; more decompositions exist.
