Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526, here are decompositions:

  • 3 + 523 = 526
  • 5 + 521 = 526
  • 17 + 509 = 526
  • 23 + 503 = 526
  • 47 + 479 = 526
  • 59 + 467 = 526
  • 83 + 443 = 526
  • 107 + 419 = 526

Showing the first eight; more decompositions exist.
