Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1554, here are decompositions:

  • 5 + 1549 = 1554
  • 11 + 1543 = 1554
  • 23 + 1531 = 1554
  • 31 + 1523 = 1554
  • 43 + 1511 = 1554
  • 61 + 1493 = 1554
  • 67 + 1487 = 1554
  • 71 + 1483 = 1554

Showing the first eight; more decompositions exist.
