Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751806, here are decompositions:

  • 3 + 8751803 = 8751806
  • 67 + 8751739 = 8751806
  • 73 + 8751733 = 8751806
  • 79 + 8751727 = 8751806
  • 139 + 8751667 = 8751806
  • 229 + 8751577 = 8751806
  • 313 + 8751493 = 8751806
  • 337 + 8751469 = 8751806

Showing the first eight; more decompositions exist.
