Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1570, here are decompositions:

  • 3 + 1567 = 1570
  • 11 + 1559 = 1570
  • 17 + 1553 = 1570
  • 47 + 1523 = 1570
  • 59 + 1511 = 1570
  • 71 + 1499 = 1570
  • 83 + 1487 = 1570
  • 89 + 1481 = 1570

Showing the first eight; more decompositions exist.
