Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500, here are decompositions:

  • 13 + 487 = 500
  • 37 + 463 = 500
  • 43 + 457 = 500
  • 61 + 439 = 500
  • 67 + 433 = 500
  • 79 + 421 = 500
  • 103 + 397 = 500
  • 127 + 373 = 500

Showing the first eight; more decompositions exist.
