Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16128, here are decompositions:

  • 17 + 16111 = 16128
  • 31 + 16097 = 16128
  • 37 + 16091 = 16128
  • 41 + 16087 = 16128
  • 59 + 16069 = 16128
  • 61 + 16067 = 16128
  • 67 + 16061 = 16128
  • 71 + 16057 = 16128

Showing the first eight; more decompositions exist.
