Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18876, here are decompositions:

  • 7 + 18869 = 18876
  • 17 + 18859 = 18876
  • 37 + 18839 = 18876
  • 73 + 18803 = 18876
  • 79 + 18797 = 18876
  • 83 + 18793 = 18876
  • 89 + 18787 = 18876
  • 103 + 18773 = 18876

Showing the first eight; more decompositions exist.
