Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616488, here are decompositions:

  • 107 + 31616381 = 31616488
  • 149 + 31616339 = 31616488
  • 191 + 31616297 = 31616488
  • 227 + 31616261 = 31616488
  • 257 + 31616231 = 31616488
  • 269 + 31616219 = 31616488
  • 359 + 31616129 = 31616488
  • 419 + 31616069 = 31616488

Showing the first eight; more decompositions exist.
