Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512, here are decompositions:

  • 3 + 509 = 512
  • 13 + 499 = 512
  • 73 + 439 = 512
  • 79 + 433 = 512
  • 103 + 409 = 512
  • 139 + 373 = 512
  • 163 + 349 = 512
  • 181 + 331 = 512

Showing the first eight; more decompositions exist.
