Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531026, here are decompositions:

  • 47 + 31530979 = 31531026
  • 53 + 31530973 = 31531026
  • 67 + 31530959 = 31531026
  • 83 + 31530943 = 31531026
  • 193 + 31530833 = 31531026
  • 199 + 31530827 = 31531026
  • 227 + 31530799 = 31531026
  • 229 + 31530797 = 31531026

Showing the first eight; more decompositions exist.
