Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627532, here are decompositions:

  • 31 + 31627501 = 31627532
  • 199 + 31627333 = 31627532
  • 229 + 31627303 = 31627532
  • 271 + 31627261 = 31627532
  • 283 + 31627249 = 31627532
  • 331 + 31627201 = 31627532
  • 463 + 31627069 = 31627532
  • 499 + 31627033 = 31627532

Showing the first eight; more decompositions exist.
