Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22018, here are decompositions:

  • 5 + 22013 = 22018
  • 41 + 21977 = 22018
  • 89 + 21929 = 22018
  • 107 + 21911 = 22018
  • 137 + 21881 = 22018
  • 167 + 21851 = 22018
  • 179 + 21839 = 22018
  • 197 + 21821 = 22018

Showing the first eight; more decompositions exist.
