Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 150, here are decompositions:

  • 11 + 139 = 150
  • 13 + 137 = 150
  • 19 + 131 = 150
  • 23 + 127 = 150
  • 37 + 113 = 150
  • 41 + 109 = 150
  • 43 + 107 = 150
  • 47 + 103 = 150

Showing the first eight; more decompositions exist.
