Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22222, here are decompositions:

  • 29 + 22193 = 22222
  • 89 + 22133 = 22222
  • 113 + 22109 = 22222
  • 131 + 22091 = 22222
  • 149 + 22073 = 22222
  • 191 + 22031 = 22222
  • 293 + 21929 = 22222
  • 311 + 21911 = 22222

Showing the first eight; more decompositions exist.
