Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17862, here are decompositions:

  • 11 + 17851 = 17862
  • 23 + 17839 = 17862
  • 71 + 17791 = 17862
  • 73 + 17789 = 17862
  • 79 + 17783 = 17862
  • 101 + 17761 = 17862
  • 113 + 17749 = 17862
  • 149 + 17713 = 17862

Showing the first eight; more decompositions exist.
