Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1536, here are decompositions:

  • 5 + 1531 = 1536
  • 13 + 1523 = 1536
  • 37 + 1499 = 1536
  • 43 + 1493 = 1536
  • 47 + 1489 = 1536
  • 53 + 1483 = 1536
  • 83 + 1453 = 1536
  • 89 + 1447 = 1536

Showing the first eight; more decompositions exist.
