Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520344, here are decompositions:

  • 5 + 31520339 = 31520344
  • 101 + 31520243 = 31520344
  • 173 + 31520171 = 31520344
  • 227 + 31520117 = 31520344
  • 467 + 31519877 = 31520344
  • 521 + 31519823 = 31520344
  • 641 + 31519703 = 31520344
  • 683 + 31519661 = 31520344

Showing the first eight; more decompositions exist.
