Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1768, here are decompositions:

  • 47 + 1721 = 1768
  • 59 + 1709 = 1768
  • 71 + 1697 = 1768
  • 101 + 1667 = 1768
  • 131 + 1637 = 1768
  • 149 + 1619 = 1768
  • 167 + 1601 = 1768
  • 197 + 1571 = 1768

Showing the first eight; more decompositions exist.
