Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17798, here are decompositions:

  • 7 + 17791 = 17798
  • 37 + 17761 = 17798
  • 61 + 17737 = 17798
  • 139 + 17659 = 17798
  • 199 + 17599 = 17798
  • 229 + 17569 = 17798
  • 307 + 17491 = 17798
  • 331 + 17467 = 17798

Showing the first eight; more decompositions exist.
