Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609396, here are decompositions:

  • 3 + 31609393 = 31609396
  • 107 + 31609289 = 31609396
  • 167 + 31609229 = 31609396
  • 173 + 31609223 = 31609396
  • 317 + 31609079 = 31609396
  • 347 + 31609049 = 31609396
  • 443 + 31608953 = 31609396
  • 479 + 31608917 = 31609396

Showing the first eight; more decompositions exist.
