Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 56280, here are decompositions:

  • 11 + 56269 = 56280
  • 13 + 56267 = 56280
  • 17 + 56263 = 56280
  • 31 + 56249 = 56280
  • 41 + 56239 = 56280
  • 43 + 56237 = 56280
  • 71 + 56209 = 56280
  • 73 + 56207 = 56280

Showing the first eight; more decompositions exist.
