Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454822, here are decompositions:

  • 13 + 31454809 = 31454822
  • 433 + 31454389 = 31454822
  • 439 + 31454383 = 31454822
  • 601 + 31454221 = 31454822
  • 631 + 31454191 = 31454822
  • 661 + 31454161 = 31454822
  • 673 + 31454149 = 31454822
  • 739 + 31454083 = 31454822

Showing the first eight; more decompositions exist.
