Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20222, here are decompositions:

  • 3 + 20219 = 20222
  • 61 + 20161 = 20222
  • 73 + 20149 = 20222
  • 79 + 20143 = 20222
  • 109 + 20113 = 20222
  • 151 + 20071 = 20222
  • 193 + 20029 = 20222
  • 199 + 20023 = 20222

Showing the first eight; more decompositions exist.
