Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8757812, here are decompositions:

  • 3 + 8757809 = 8757812
  • 13 + 8757799 = 8757812
  • 43 + 8757769 = 8757812
  • 241 + 8757571 = 8757812
  • 433 + 8757379 = 8757812
  • 439 + 8757373 = 8757812
  • 523 + 8757289 = 8757812
  • 691 + 8757121 = 8757812

Showing the first eight; more decompositions exist.
