Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609224, here are decompositions:

  • 11 + 31609213 = 31609224
  • 107 + 31609117 = 31609224
  • 113 + 31609111 = 31609224
  • 131 + 31609093 = 31609224
  • 137 + 31609087 = 31609224
  • 191 + 31609033 = 31609224
  • 193 + 31609031 = 31609224
  • 271 + 31608953 = 31609224

Showing the first eight; more decompositions exist.
