Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 496, here are decompositions:

  • 5 + 491 = 496
  • 17 + 479 = 496
  • 29 + 467 = 496
  • 47 + 449 = 496
  • 53 + 443 = 496
  • 107 + 389 = 496
  • 113 + 383 = 496
  • 137 + 359 = 496

Showing the first eight; more decompositions exist.
