Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 560, here are decompositions:

  • 3 + 557 = 560
  • 13 + 547 = 560
  • 19 + 541 = 560
  • 37 + 523 = 560
  • 61 + 499 = 560
  • 73 + 487 = 560
  • 97 + 463 = 560
  • 103 + 457 = 560

Showing the first eight; more decompositions exist.
