Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27220, here are decompositions:

  • 23 + 27197 = 27220
  • 29 + 27191 = 27220
  • 41 + 27179 = 27220
  • 113 + 27107 = 27220
  • 227 + 26993 = 27220
  • 233 + 26987 = 27220
  • 239 + 26981 = 27220
  • 269 + 26951 = 27220

Showing the first eight; more decompositions exist.
