Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709440, here are decompositions:

67 + 8709373 = 8709440
79 + 8709361 = 8709440
127 + 8709313 = 8709440
139 + 8709301 = 8709440
151 + 8709289 = 8709440
211 + 8709229 = 8709440
307 + 8709133 = 8709440
373 + 8709067 = 8709440

Showing the first eight; more decompositions exist.
