Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582204, here are decompositions:

  • 11 + 31582193 = 31582204
  • 41 + 31582163 = 31582204
  • 83 + 31582121 = 31582204
  • 107 + 31582097 = 31582204
  • 167 + 31582037 = 31582204
  • 257 + 31581947 = 31582204
  • 293 + 31581911 = 31582204
  • 443 + 31581761 = 31582204

Showing the first eight; more decompositions exist.
