Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1598, here are decompositions:

  • 19 + 1579 = 1598
  • 31 + 1567 = 1598
  • 67 + 1531 = 1598
  • 109 + 1489 = 1598
  • 127 + 1471 = 1598
  • 139 + 1459 = 1598
  • 151 + 1447 = 1598
  • 199 + 1399 = 1598

Showing the first eight; more decompositions exist.
