Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 584, here are decompositions:

  • 7 + 577 = 584
  • 13 + 571 = 584
  • 37 + 547 = 584
  • 43 + 541 = 584
  • 61 + 523 = 584
  • 97 + 487 = 584
  • 127 + 457 = 584
  • 151 + 433 = 584

Showing the first eight; more decompositions exist.
