Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8755280, here are decompositions:

  • 3 + 8755277 = 8755280
  • 13 + 8755267 = 8755280
  • 103 + 8755177 = 8755280
  • 139 + 8755141 = 8755280
  • 349 + 8754931 = 8755280
  • 367 + 8754913 = 8755280
  • 397 + 8754883 = 8755280
  • 409 + 8754871 = 8755280

Showing the first eight; more decompositions exist.
