Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616664, here are decompositions:

  • 17 + 31616647 = 31616664
  • 41 + 31616623 = 31616664
  • 61 + 31616603 = 31616664
  • 103 + 31616561 = 31616664
  • 241 + 31616423 = 31616664
  • 263 + 31616401 = 31616664
  • 271 + 31616393 = 31616664
  • 283 + 31616381 = 31616664

Showing the first eight; more decompositions exist.
