Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12874, here are decompositions:

  • 53 + 12821 = 12874
  • 83 + 12791 = 12874
  • 131 + 12743 = 12874
  • 227 + 12647 = 12874
  • 233 + 12641 = 12874
  • 263 + 12611 = 12874
  • 347 + 12527 = 12874
  • 383 + 12491 = 12874

Showing the first eight; more decompositions exist.
