Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1650, here are decompositions:

  • 13 + 1637 = 1650
  • 23 + 1627 = 1650
  • 29 + 1621 = 1650
  • 31 + 1619 = 1650
  • 37 + 1613 = 1650
  • 41 + 1609 = 1650
  • 43 + 1607 = 1650
  • 53 + 1597 = 1650

Showing the first eight; more decompositions exist.
