Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20270, here are decompositions:

  • 37 + 20233 = 20270
  • 97 + 20173 = 20270
  • 109 + 20161 = 20270
  • 127 + 20143 = 20270
  • 157 + 20113 = 20270
  • 163 + 20107 = 20270
  • 181 + 20089 = 20270
  • 199 + 20071 = 20270

Showing the first eight; more decompositions exist.
