Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17892, here are decompositions:

  • 11 + 17881 = 17892
  • 29 + 17863 = 17892
  • 41 + 17851 = 17892
  • 53 + 17839 = 17892
  • 101 + 17791 = 17892
  • 103 + 17789 = 17892
  • 109 + 17783 = 17892
  • 131 + 17761 = 17892

Showing the first eight; more decompositions exist.
