Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 514, here are decompositions:

  • 5 + 509 = 514
  • 11 + 503 = 514
  • 23 + 491 = 514
  • 47 + 467 = 514
  • 53 + 461 = 514
  • 71 + 443 = 514
  • 83 + 431 = 514
  • 113 + 401 = 514

Showing the first eight; more decompositions exist.
