Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47018, here are decompositions:

  • 61 + 46957 = 47018
  • 151 + 46867 = 47018
  • 157 + 46861 = 47018
  • 199 + 46819 = 47018
  • 211 + 46807 = 47018
  • 271 + 46747 = 47018
  • 331 + 46687 = 47018
  • 337 + 46681 = 47018

Showing the first eight; more decompositions exist.
