Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12280, here are decompositions:

  • 3 + 12277 = 12280
  • 11 + 12269 = 12280
  • 17 + 12263 = 12280
  • 29 + 12251 = 12280
  • 41 + 12239 = 12280
  • 53 + 12227 = 12280
  • 83 + 12197 = 12280
  • 131 + 12149 = 12280

Showing the first eight; more decompositions exist.
