Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526876, here are decompositions:

  • 13 + 31526863 = 31526876
  • 67 + 31526809 = 31526876
  • 103 + 31526773 = 31526876
  • 127 + 31526749 = 31526876
  • 163 + 31526713 = 31526876
  • 229 + 31526647 = 31526876
  • 313 + 31526563 = 31526876
  • 349 + 31526527 = 31526876

Showing the first eight; more decompositions exist.
