Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751886, here are decompositions:

  • 23 + 8751863 = 8751886
  • 47 + 8751839 = 8751886
  • 83 + 8751803 = 8751886
  • 113 + 8751773 = 8751886
  • 137 + 8751749 = 8751886
  • 257 + 8751629 = 8751886
  • 293 + 8751593 = 8751886
  • 359 + 8751527 = 8751886

Showing the first eight; more decompositions exist.
