Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 536, here are decompositions:

  • 13 + 523 = 536
  • 37 + 499 = 536
  • 73 + 463 = 536
  • 79 + 457 = 536
  • 97 + 439 = 536
  • 103 + 433 = 536
  • 127 + 409 = 536
  • 139 + 397 = 536

Showing the first eight; more decompositions exist.
