Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18012, here are decompositions:

  • 23 + 17989 = 18012
  • 31 + 17981 = 18012
  • 41 + 17971 = 18012
  • 53 + 17959 = 18012
  • 73 + 17939 = 18012
  • 83 + 17929 = 18012
  • 89 + 17923 = 18012
  • 101 + 17911 = 18012

Showing the first eight; more decompositions exist.
