Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542740, here are decompositions:

  • 13 + 31542727 = 31542740
  • 37 + 31542703 = 31542740
  • 43 + 31542697 = 31542740
  • 109 + 31542631 = 31542740
  • 127 + 31542613 = 31542740
  • 181 + 31542559 = 31542740
  • 193 + 31542547 = 31542740
  • 283 + 31542457 = 31542740

Showing the first eight; more decompositions exist.
