Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17908, here are decompositions:

  • 5 + 17903 = 17908
  • 17 + 17891 = 17908
  • 71 + 17837 = 17908
  • 101 + 17807 = 17908
  • 179 + 17729 = 17908
  • 227 + 17681 = 17908
  • 239 + 17669 = 17908
  • 251 + 17657 = 17908

Showing the first eight; more decompositions exist.
