Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1610, here are decompositions:

  • 3 + 1607 = 1610
  • 13 + 1597 = 1610
  • 31 + 1579 = 1610
  • 43 + 1567 = 1610
  • 61 + 1549 = 1610
  • 67 + 1543 = 1610
  • 79 + 1531 = 1610
  • 127 + 1483 = 1610

Showing the first eight; more decompositions exist.
