Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625008, here are decompositions:

  • 29 + 31624979 = 31625008
  • 101 + 31624907 = 31625008
  • 179 + 31624829 = 31625008
  • 227 + 31624781 = 31625008
  • 269 + 31624739 = 31625008
  • 347 + 31624661 = 31625008
  • 449 + 31624559 = 31625008
  • 461 + 31624547 = 31625008

Showing the first eight; more decompositions exist.
