Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609358, here are decompositions:

  • 19 + 31609339 = 31609358
  • 127 + 31609231 = 31609358
  • 241 + 31609117 = 31609358
  • 271 + 31609087 = 31609358
  • 421 + 31608937 = 31609358
  • 541 + 31608817 = 31609358
  • 601 + 31608757 = 31609358
  • 631 + 31608727 = 31609358

Showing the first eight; more decompositions exist.
