Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 570, here are decompositions:

  • 7 + 563 = 570
  • 13 + 557 = 570
  • 23 + 547 = 570
  • 29 + 541 = 570
  • 47 + 523 = 570
  • 61 + 509 = 570
  • 67 + 503 = 570
  • 71 + 499 = 570

Showing the first eight; more decompositions exist.
