Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1534, here are decompositions:

  • 3 + 1531 = 1534
  • 11 + 1523 = 1534
  • 23 + 1511 = 1534
  • 41 + 1493 = 1534
  • 47 + 1487 = 1534
  • 53 + 1481 = 1534
  • 83 + 1451 = 1534
  • 101 + 1433 = 1534

Showing the first eight; more decompositions exist.
