Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616326, here are decompositions:

  • 29 + 31616297 = 31616326
  • 107 + 31616219 = 31616326
  • 197 + 31616129 = 31616326
  • 257 + 31616069 = 31616326
  • 293 + 31616033 = 31616326
  • 317 + 31616009 = 31616326
  • 347 + 31615979 = 31616326
  • 353 + 31615973 = 31616326

Showing the first eight; more decompositions exist.
