Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751172, here are decompositions:

  • 29 + 8751143 = 8751172
  • 71 + 8751101 = 8751172
  • 83 + 8751089 = 8751172
  • 239 + 8750933 = 8751172
  • 251 + 8750921 = 8751172
  • 281 + 8750891 = 8751172
  • 389 + 8750783 = 8751172
  • 401 + 8750771 = 8751172

Showing the first eight; more decompositions exist.
