Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17658, here are decompositions:

  • 31 + 17627 = 17658
  • 59 + 17599 = 17658
  • 61 + 17597 = 17658
  • 79 + 17579 = 17658
  • 89 + 17569 = 17658
  • 107 + 17551 = 17658
  • 139 + 17519 = 17658
  • 149 + 17509 = 17658

Showing the first eight; more decompositions exist.
