Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17902, here are decompositions:

  • 11 + 17891 = 17902
  • 113 + 17789 = 17902
  • 173 + 17729 = 17902
  • 233 + 17669 = 17902
  • 293 + 17609 = 17902
  • 383 + 17519 = 17902
  • 419 + 17483 = 17902
  • 431 + 17471 = 17902

Showing the first eight; more decompositions exist.
