Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4536, here are decompositions:

  • 13 + 4523 = 4536
  • 17 + 4519 = 4536
  • 19 + 4517 = 4536
  • 23 + 4513 = 4536
  • 29 + 4507 = 4536
  • 43 + 4493 = 4536
  • 53 + 4483 = 4536
  • 73 + 4463 = 4536

Showing the first eight; more decompositions exist.
