Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1500, here are decompositions:

  • 7 + 1493 = 1500
  • 11 + 1489 = 1500
  • 13 + 1487 = 1500
  • 17 + 1483 = 1500
  • 19 + 1481 = 1500
  • 29 + 1471 = 1500
  • 41 + 1459 = 1500
  • 47 + 1453 = 1500

Showing the first eight; more decompositions exist.
