Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8758440, here are decompositions:

  • 7 + 8758433 = 8758440
  • 11 + 8758429 = 8758440
  • 13 + 8758427 = 8758440
  • 79 + 8758361 = 8758440
  • 101 + 8758339 = 8758440
  • 107 + 8758333 = 8758440
  • 113 + 8758327 = 8758440
  • 127 + 8758313 = 8758440

Showing the first eight; more decompositions exist.
