Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485632, here are decompositions:

  • 313 + 31485319 = 31485632
  • 331 + 31485301 = 31485632
  • 349 + 31485283 = 31485632
  • 439 + 31485193 = 31485632
  • 601 + 31485031 = 31485632
  • 613 + 31485019 = 31485632
  • 631 + 31485001 = 31485632
  • 643 + 31484989 = 31485632

Showing the first eight; more decompositions exist.
