Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499632, here are decompositions:

  • 11 + 31499621 = 31499632
  • 71 + 31499561 = 31499632
  • 173 + 31499459 = 31499632
  • 233 + 31499399 = 31499632
  • 401 + 31499231 = 31499632
  • 443 + 31499189 = 31499632
  • 449 + 31499183 = 31499632
  • 569 + 31499063 = 31499632

Showing the first eight; more decompositions exist.
