Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18078, here are decompositions:

  • 17 + 18061 = 18078
  • 19 + 18059 = 18078
  • 29 + 18049 = 18078
  • 31 + 18047 = 18078
  • 37 + 18041 = 18078
  • 89 + 17989 = 18078
  • 97 + 17981 = 18078
  • 101 + 17977 = 18078

Showing the first eight; more decompositions exist.
