Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 510, here are decompositions:

  • 7 + 503 = 510
  • 11 + 499 = 510
  • 19 + 491 = 510
  • 23 + 487 = 510
  • 31 + 479 = 510
  • 43 + 467 = 510
  • 47 + 463 = 510
  • 53 + 457 = 510

Showing the first eight; more decompositions exist.
