Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530398, here are decompositions:

  • 7 + 31530391 = 31530398
  • 337 + 31530061 = 31530398
  • 397 + 31530001 = 31530398
  • 421 + 31529977 = 31530398
  • 499 + 31529899 = 31530398
  • 727 + 31529671 = 31530398
  • 769 + 31529629 = 31530398
  • 859 + 31529539 = 31530398

Showing the first eight; more decompositions exist.
