Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550836, here are decompositions:

  • 3 + 31550833 = 31550836
  • 29 + 31550807 = 31550836
  • 89 + 31550747 = 31550836
  • 113 + 31550723 = 31550836
  • 137 + 31550699 = 31550836
  • 263 + 31550573 = 31550836
  • 293 + 31550543 = 31550836
  • 389 + 31550447 = 31550836

Showing the first eight; more decompositions exist.
