Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1526, here are decompositions:

  • 3 + 1523 = 1526
  • 37 + 1489 = 1526
  • 43 + 1483 = 1526
  • 67 + 1459 = 1526
  • 73 + 1453 = 1526
  • 79 + 1447 = 1526
  • 97 + 1429 = 1526
  • 103 + 1423 = 1526

Showing the first eight; more decompositions exist.
