Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586704, here are decompositions:

  • 5 + 31586699 = 31586704
  • 113 + 31586591 = 31586704
  • 167 + 31586537 = 31586704
  • 257 + 31586447 = 31586704
  • 353 + 31586351 = 31586704
  • 431 + 31586273 = 31586704
  • 467 + 31586237 = 31586704
  • 557 + 31586147 = 31586704

Showing the first eight; more decompositions exist.
