Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17868, here are decompositions:

  • 5 + 17863 = 17868
  • 17 + 17851 = 17868
  • 29 + 17839 = 17868
  • 31 + 17837 = 17868
  • 41 + 17827 = 17868
  • 61 + 17807 = 17868
  • 79 + 17789 = 17868
  • 107 + 17761 = 17868

Showing the first eight; more decompositions exist.
