Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620902, here are decompositions:

  • 5 + 8620897 = 8620902
  • 29 + 8620873 = 8620902
  • 41 + 8620861 = 8620902
  • 61 + 8620841 = 8620902
  • 163 + 8620739 = 8620902
  • 179 + 8620723 = 8620902
  • 181 + 8620721 = 8620902
  • 211 + 8620691 = 8620902

Showing the first eight; more decompositions exist.
