Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15964, here are decompositions:

  • 5 + 15959 = 15964
  • 41 + 15923 = 15964
  • 83 + 15881 = 15964
  • 167 + 15797 = 15964
  • 173 + 15791 = 15964
  • 191 + 15773 = 15964
  • 197 + 15767 = 15964
  • 227 + 15737 = 15964

Showing the first eight; more decompositions exist.
