Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576604, here are decompositions:

  • 127 + 31576477 = 31576604
  • 151 + 31576453 = 31576604
  • 193 + 31576411 = 31576604
  • 337 + 31576267 = 31576604
  • 373 + 31576231 = 31576604
  • 487 + 31576117 = 31576604
  • 601 + 31576003 = 31576604
  • 613 + 31575991 = 31576604

Showing the first eight; more decompositions exist.
