Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563022, here are decompositions:

  • 41 + 31562981 = 31563022
  • 173 + 31562849 = 31563022
  • 311 + 31562711 = 31563022
  • 401 + 31562621 = 31563022
  • 419 + 31562603 = 31563022
  • 479 + 31562543 = 31563022
  • 503 + 31562519 = 31563022
  • 521 + 31562501 = 31563022

Showing the first eight; more decompositions exist.
