Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564384, here are decompositions:

  • 23 + 31564361 = 31564384
  • 53 + 31564331 = 31564384
  • 113 + 31564271 = 31564384
  • 227 + 31564157 = 31564384
  • 251 + 31564133 = 31564384
  • 281 + 31564103 = 31564384
  • 431 + 31563953 = 31564384
  • 443 + 31563941 = 31564384

Showing the first eight; more decompositions exist.
