Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539196, here are decompositions:

  • 5 + 31539191 = 31539196
  • 53 + 31539143 = 31539196
  • 107 + 31539089 = 31539196
  • 113 + 31539083 = 31539196
  • 149 + 31539047 = 31539196
  • 389 + 31538807 = 31539196
  • 443 + 31538753 = 31539196
  • 467 + 31538729 = 31539196

Showing the first eight; more decompositions exist.
