Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526270, here are decompositions:

  • 31 + 31526239 = 31526270
  • 43 + 31526227 = 31526270
  • 73 + 31526197 = 31526270
  • 79 + 31526191 = 31526270
  • 313 + 31525957 = 31526270
  • 367 + 31525903 = 31526270
  • 379 + 31525891 = 31526270
  • 421 + 31525849 = 31526270

Showing the first eight; more decompositions exist.
