Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586222, here are decompositions:

  • 163 + 31586059 = 31586222
  • 373 + 31585849 = 31586222
  • 439 + 31585783 = 31586222
  • 643 + 31585579 = 31586222
  • 673 + 31585549 = 31586222
  • 769 + 31585453 = 31586222
  • 823 + 31585399 = 31586222
  • 853 + 31585369 = 31586222

Showing the first eight; more decompositions exist.
