Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 160, here are decompositions:

  • 3 + 157 = 160
  • 11 + 149 = 160
  • 23 + 137 = 160
  • 29 + 131 = 160
  • 47 + 113 = 160
  • 53 + 107 = 160
  • 59 + 101 = 160
  • 71 + 89 = 160

Showing the first eight; more decompositions exist.
