Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687902, here are decompositions:

  • 11 + 8687891 = 8687902
  • 23 + 8687879 = 8687902
  • 29 + 8687873 = 8687902
  • 131 + 8687771 = 8687902
  • 173 + 8687729 = 8687902
  • 233 + 8687669 = 8687902
  • 389 + 8687513 = 8687902
  • 449 + 8687453 = 8687902

Showing the first eight; more decompositions exist.
